Description
This toolbox allows you to load into Scilab .nl files created using AMPL (http://www.ampl.com). Once loaded
into Scilab, you can use them like any other objective functions, get derivatives, constraints, etc. You can use
Scilab optimization tools to find some solutions. You must compile ampl .mod files into .nl files before using this
toolbox to load the file into Scilab.



This represents a toolbox for artificial neural networks, based on my developments described in "Matrix ANN"
book, under development, if interested send me an email at r.hristev@phys.canterbury.ac.nz Current features -
Only layered feedforward networks are supported *directly* at the moment (for others use the "hooks"
provided) - Unlimited number of layers - Unlimited number of neurons per each layer separately - User defined
activation function (defaults to logistic) - User defined error function (defaults to SSE) - Algorithms implemented
so far: * standard (vanilla) with or without bias, on-line or batch * momentum with or without bias, on-line or
Purpose The goal of this module is to provide a set to function to check input arguments in macros. In
functions with a variable number of input arguments, we often have the following source code, which checks
that the number of input arguments provided by the user is consistent with the number of expected arguments
: [lhs,rhs]=argn() if ( rhs < 2 | rhs > 5 ) then errmsg = msprintf(gettext("%s: Unexpected number of input
arguments : %d provided while from %d to %d are expected."), "myfunnction", rhs,2,5); error(errmsg) end
Writing this code is error-prone and boring. Moreover, this fragment of source code is duplicated in many
functions, leading to small variations depending on the developer. In particular, this makes the localization of
the error messages difficult, because the message can be slightly different depending on the function. It can also
Purpose ---- The goal of this toolbox is to provide assert function. We emphasize the numerical issues, with the
goal of testing numerical algorithms more easily. In particular, we provide a comparison function for two
floating point numbers, which allows to assert that two numbers are "close" (including, but not limited to,
equal). The function of the assert module are designed to be used in Scilab unit tests files (.tst files). The
following is a list of the current features: * assert for true, equal statements * assert that two floating point
numbers are "close". Use an relative or a absolute tolerance * provide a sorting function for double complex
numbers with a mixed relative/absolute tolerance criteria. The following is a list of the current assert functions :
 * assert_almostequal : Check that computed and expected are numerically close. * assert_equal : Check that
CelestLab is a library of space flight dynamics functions written in Scilab. This library has been developed and is
maintained by CNES (Centre National d’Etudes Spatiales) for mission analysis purposes. The library is used by
CNES for the trajectory analysis and orbit design of various missions. CelestLab gathers in ten modules about
200 functions that allow mission designers to perform various tasks such as: orbit propagation, attitude
computation, elementary manoeuvre computation, change of reference frames, change of coordinates, three
The CONMIN optimization method is currently used in NASTRAN (a professionnal finite element tool) and the
optimization part of NASTRAN (the CONMIN tool) is currently public domain. The CONMIN fortran program has
been written by G. Vanderplaats. This optimization method can solve efficiently constrained optimization
problems.

DACE, Design and Analysis of Computer Experiments, is a Matlab toolbox for working with kriging
approximations to computer models. Typical use of this software is to construct a kriging approximation model
based on data from a computer experiment, and to use this approximation model as a surrogate for the
computer model. The software also addresses the design of experiment problem, that is choosing the inputs at
which to evaluate the computer model for constructing the kriging approximation.

Toolbox for Empirical Mode Decomposition of 1-D, 2-D and more dimensional signals. Summary from Wikipedia
(http://en.wikipedia.org/wiki/Hilbert%E2%80%93Huang_transform): Using the EMD method, any complicated
data set can be decomposed into a finite and often small number of components, which is a collection of
intrinsic mode functions (IMF). An IMF represents a generally simple oscillatory mode as a counterpart to the
simple harmonic function. By definition, an IMF is any function with the same number of extrema and zero
crossings, with its envelopes being symmetric with respect to zero. The definition of an IMF guarantees a well-
behaved Hilbert transform of the IMF. This decomposition method operating in the time domain is adaptive
and highly efficient. Since the decomposition is based on the local characteristic time scale of the data, it can be
applied to nonlinear and nonstationary processes.
A Truss finite element code for scilab. In the demos directory, you will find some demos related to structural

The module is dedicated to finance. There are three main areas that are covered: (i) risk measure and
management, (ii) asset allocation, and (iii) pricing. For what concerns the risk measure, some functions are
dedicated to the computation of Value at Risk (VaR) and Expected Shortfall (ES). Backtest is also implemented in
order to check the goodness of such risk measures. Both VaR and ES are also computed in an Extreme Value
Theory framework (EVT). Furthermore, it is possible to estimate the parameters of the EVT density function
(through maximum likelihood). The Mean Excess Function for graphical study of an EVT distribution is also
implemented. The interest rate risk is faced by functions aimed at computing duration, convexity, and yield to
maturity. Furthermore, Merton, Vasicek and Cox, Ingersoll and Ross interest rate models are implemented
Floating Point toolbox Purpose The goal of this toolbox is to provide a collection of algorithms for floating point
number management. This is more a learning tool than an operationnal component, although it might
complement some features which are not provided by Scilab. The flps_systemgui function allows to see the
distribution of floating point numbers graphically. By varying the rounding mode, the precision and the logscale,
we can actually the distribution of a toy floating point number. Adding or suppressing the denormals can be
instructive too. The functions allow to compute automatically the properties of the current Scilab system with
respect to the doubles. It is similar in spirit to the number_properties functions, except that our functions are
based on macros and that the returned values are made consistent with the references cited in the
Purpose The goal of this toolbox is to provide a fmincon function in Scilab. The fmincon function is a
nonlinearily constrained optimization solver. Currently, we use ipopt for the actual solver of fmincon. The
current state of the function is experimental. Many features are yet to be implemented. We provide upgraded
versions of the optimset and optimget functions, which manage options which are required by fmincon. The
current implementation is able to manage the following use cases. We use a L-BFGS formula in order to
compute an approximate of the Hessian of the Lagrangian. (0) The initial guess is provided in the x0 input
argument. (1) The nonlinear objective function and the nonlinear constraints are provided. The fun and nonlcon
function can be customized to configure the nonlinear objective function and nonlinear constraints. In this case,

Many problems in science and engineering can be reduced to the problem of finding optimum bounds for the
range of a multivariable polynomial on a specified domain. Local optimization is an important tool for solving
polynomial problems, but there is no guarantee of global optimality. For polynomial optimization problems, an
alternate approach is based on the Bernstein form of the polynomial. If a polynomial is written in the Bernstein
basis over a box, then the range of the polynomial is bounded by the values of the minimum and maximum
Bernstein coefficients. Global optimization based on the Bernstein form does not require the iterative
evaluation of the objective function. Moreover, the coefficients of the Bernstein form are needed to be
computed only once, i.e., only on the initial domain box. The Bernstein coefficients for the subdivided domain
boxes can then be obtained from the initial box itself. Capturing these beautiful properties of the Bernstein
polynomials, global optimum for the polynomial on the given domain can be obtained. The toolbox is developed
based on the above ideas.

HYDROGR is a set of models and function to perform data analysis and modelling of hydrological time series. In
particular HYDROGR contains the rainfall-runoff model GR4J developped in CEMAGREF (see
http://www.cemagref.fr/webgr/index.htm). The functions are written in Scilab languages and C

Purpose The goal of this toolbox is to provide integration test problems in order to test integration algorithms.
This allows to test integration algorithms on a larger base of functions. Developping these functions is error-
prone, so that using this module allows to save much time. Moreover, testing an algorithm leads to the difficulty
of chosing a set of test functions. But all functions are not equally difficult to integrate; while some are simple,
other might be particularily difficult, leading to poor results. Comparing two algorithms, each on a different set
of functions will not lead to an accurate view of the algorithm. This module allows to compare the algorithms
more precisely. In spirit, this module has the same motivations as the Unconstrained Optimization Scilab
toolbox based on the More, Garbow and Hillstrom collection of functions. Overview The module currently
The Lolimot model (LOcal LInear MOdel Tree) is a model from the neural network familly. It is able to learn
every kind of non-linear relationship. Compared to a classical neural network, the learning phase of a LOLIMOT
model is quite fast and deterministic. Once a model is learnt, you have an easy access to analytical derivatives of
your model through a call to the function estim_der_lolimot.


The goal of this toolbox is to provide a collection of low discrepancy sequences. These random numbers are
designed to be used in a Monte-Carlo simulation. For example, low discrepancy sequences provide a higher
convergence rate to the Monte-Carlo method when used in numerical integration. The toolbox takes into
account the dimension of the problem, i.e. generate vectors with arbitrary size. The current prototype has the
following features : * manage arbitrary number of dimensions, * skips a given number of elements in the
sequence, * leaps (i.e. ignores) a given number of elements from call to call, * fast sequences based on compiled
source code, * suggest optimal settings to use the best of the sequences, * object oriented programming.

There are 2 functions. log_fir() calculates phase of a minimum phase function having specified gain. It utilizes
the fact that exp(a0+a1/z+a2/z^2+..) is the minimum phase function. The gain is exp(a0+a1*cos(w)+..) and the
phase is exp(-(a1*sin(w)+..)). So by selecting a0,a1,.. from the specified gain, the phase can be obtained. piir()
calculates the stable IIR filter from the specified phase. The method is shown in. M.Kisaka: Phase design of an
IIR filter and its application to an inverse system, Proceeding of the 2006 IEEE international conference on
control system,Munich, Germany,Oct.2619/2622(2006)

Sci2C is a tool capable to translate Scilab code into C code. It is a standalone toolbox of Scilab and it has been
primarily developed to become the interface between the Scilab scientific software package and the hArtes
design flow. The output C code is in a plain style and does not include any part of the Scilab interpreter thus
making it small, efficient and easy to interface to the hArtes tool chain. In other words, the generated C code is
standalone and minimal in the sense that Scilab interpreter is no longer needed and only the minimal number of
C files which are necessary to execute the application are generated. It follows that the generated code can be
embedded in processors or used as entries for other software. Sci2C is implemented in Scilab language, so it
naturally becomes a Scilab toolbox available in the Scilab installation program and consequently it can be
scipad (atoms format)

done outside of the script.
