Mathematics

Scilab provides about 1,700 mathematical functions for usual engineering and science applications including mathematical operations and data analysis.

Elementary functions

// x initialisation
x=[0:0.1:2*%pi]';
//simple plot
plot(sin(x))

Polynomials and rational functions    

//seed for defining polynomials
with symbol "s"
s=poly(0,"s");p=1+s+2*s^2;

Vectors and Matrixes

The core of Scilab is based on linear algebra librairies.
It is optimized for matrix computations.
