Scilab
 another laboratory for matrices and number crunching
It
is always good to be able to work in different environments. There are
several numerical tools that offer plenty of functions to work with
matrices, arrays, structures and powerful visualization capabilities.
This section explores some basic ideas to work with a SCIence
LABoratory.
Basic Commands and Data Types
We'll explore builtin functions and data types, with simple lines of
code.
The IF Statement
The IF statement lets you evaluate a condition and works
together with the THEN clause to take a course of action based on...
Branching  Select Case
The common Switch statement becomes the Select Case statement in
Scilab, compare it with the Matlab switch case.
2D plots
Basic functions to create easy 2Dplots.
Functions and Scripts
In past years they were called subroutines...
Scilab Examples  2D summary
Several
types of plots in Scilab: single and multiple plots, pies, histograms,
etc. A practical approach with solutions, not only problems.
Piecewise Functions
See one method to create piecewise functions. See how to vectorize
pieces and plot them.
3D Plots
Explore some features for 3D plotting. You'll learn about parametric
curves, meshgrids and other special builtin functions.
Recursion in Scilab A brief experiment with the factorial function.
Integral Calculator
Calculate definite integrals using intg or int2d functions for
this purpose.
Scilab and Scicos Books
