# equal

(=) assignment , comparison, equal sign

### 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```
