(=) assignment , comparison, equal sign



The equal sign = is used to denote the assignment of value(s) to variable(s). The syntax can be :

  • a=expr where a is a variable name and expr a scilab expression which evaluates to a single result;

  • [a,b,...]=expr where a,b,... are variable names and expr a scilab expression which results in as many results as given variable names.


The equal sign = is also used in the comparison operators:

  • a==b denotes equality comparison between the values of the expressions a and b;

  • a~=b denotes inequality comparison between the values of the expressions a and b;

  • a<=b and a>=b denote ordering comparison between the values of the expressions a and b.

See comparison for semantic details.


a = sin(3.2)
M = [2.1,3.3,8.5;7.6,6.7,6.9;0,6.3,8.8];
[u,s] = schur(M)
2*2 == 4
[1:10] == 4
"foo" == "bar"
sparse([1,2;4,5;3,10],[1,2,3]) == sparse([1,2;4,5;3,10],[1,2,3])

6.0 ~ (not) priority is now higher than the comparisons one (== ~= <= >=). For instance, ~%t==1 is parsed as (~%t)==1 instead of ~(%t==1) and now yields %F instead of %T.
