Comparison Operators

The comparison (relational) operators return1 for true and 0for false. These operators
are

< Less than

> Greater than

< = Less than or equalto

> = Greater than or equalto

== Equalto
˜= Not equalto

The comparison operators always act element-wise onmatrices; hence theyresult in
amatrix of logical type.For example,

>>A=[123;456];B=[789;012];
>>A>B
ans =

0 0 0

1 1 1

Logical Operators

The logicaloperators in MATLAB are

& AND
|

OR
˜ NOT

Theyare used to build compound relationalexpressions, an example of which is
shown below.

>>A=[123;456];B=[789;012];
>>(A>B)

|

(B>5)

ans =

1 1 1

1 1 1
