Starting Scilab

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
res1 =

- 1.

-->res2 = (x + y)*z
res2 =

2.

-->res3 = (-x + y)/z
res3 =

0.5


With the 4 arithmetic operations, we can do any numeric simulation.

In next posts, I'll show what the Scilab can do.
