# Like MALAB there are some more software packages which are also user friendly with so many toolboxes. I am naming some of th software like SCILAB, Python, Mathematica, Octave, and R. These software are free and almost having C/MATLAB syntax. It is easier to change the syntax between these programming languages.

# In this page I am giving a general introduction about scilab

# What is Scilab?

Developed at INRIA, Scilab has been developed for system control and signal processing applications. It is freely distributed in source code format (see the copyright file).A key feature of the Scilab syntax is its ability to handle matrices:

Polynomials, polynomials matrices and transfer matrices are also defined and the syntax used for manipulating these matrices is identical to that used for manipulating constant vectors and matrices.

Scilab provides a variety of powerful primitives for the analysis of non-linear systems. Integration of explicit and implicit dynamic systems can be accomplished numerically.

The scicos(similar to simulink) toolbox allows the graphic definition and simulation of complex interconnected hybrid systems.

There exist numerical optimization facilities for non linear optimization (including non differentiable optimization), quadratic optimization and linear optimization.

Scilab has an open programming environment where the creation of functions and libraries of functions is completely in the hands of the user.

Finally, Scilab is easily interfaced with Fortran or C subprograms. This allows use of standardized packages and libraries in the interpreted environment of Scilab.

The scilab can be downloaded form the following link.

The site gives detailed documentation also.

I will post some programs in scilab to solve some optimization problems soon.

Download scilab and install it. All the best
