The first step for use Scilab is install it.
GNU/Linux users can use the apt-get (apt-get install scilab scilab-bin scilab-doc), Synaptic or compile the codes (from here).
Window$ users can download the installer here.
After install, let's use the Scilab.
This is the initial screen.
Scilab is a interpreted programming language like Python.
The showed screen is the Scilab's prompt, let's do something now.
Write the commands:
--> x = 0;
--> y = 1;
--> z = 2;
Each line declares a variable (x, y and z) and starts it value with 0, 1 and 2, respectively, in float format (in Scilab, all numbers are float, by default).
Let's do operations with the variables now.
-->res1 = x + y - z
-->res2 = (x + y)*z
-->res3 = (-x + y)/z
With the 4 arithmetic operations, we can do any numeric simulation.
In next posts, I'll show what the Scilab can do.
