equal

Description

Assignment:

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.

Comparison:

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.

Examples

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])
1~=2
