Question

What is the meaning of the dollar symbol ($) in SciLab?

EDIT: I meant the dollar symbol used in indices. I assumed that this is his only use.

Answer 1

The dollar symbol can be used to indicate the last element of any vector or matrix.

-->A = [1 2 3 4 5]
 A  =

    1.    2.    3.    4.    5.  

-->A($)
 ans  =

    5.  

-->A($-1)
 ans  =

    4.  

Answer 2

According to the documentation , dollar signs are used to distinguish between embedded LaTeX .

Starting with Scilab 5.2, you can write LaTeX or MathML expression.

LaTeX texts must begin and end with $ (dollar symbol), while MathML texts must begin with <and end with> and be syntactically valid.

Answer 3

- ( ), .

-->a = list()
 a  =
     ()
-->a(5) = 100
 a  =
// ...
-->a($)
 ans  =
    100.
