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.

Hi, I trying to find how can I insert an entry at scilab like 1/2, and the output is show me exactly 1/2, not the evaluated valor 0.5. In Maxima program, it can be changed setting the numer internal variable to false or true. Thank you!

hello,im muszle ...

im looking for a sample coding for PID controller tuning...anybody know how to start typing it?
