The Scilab is a simulation enviroment to numeric computation, i. e., the Scilab have many resources to solve complicated problems.
Examples of aplications that I work in Scilab:
- Neural networks;
- Genetics Algorithms;
- Analysis os temporal series (in economy);
- Digital images and signals processing;
- Computational vision;
The Scilab has many toolboxes, for example: SIVP - Scilab Image and Video Processing toolbox and SWT - Scilab Wavelets Toolbox (this have functions for signals and images). The Scicos is a graphical simulation enviroment, this is on the Scilab (called by "scicos" in prompt), with the Scicos is possible to develop "getting blocks", this is a easy and fast mode to work.
To finish, the Scilab is a free software and doesn't have less resources than proprietary softwares.
