Comparison operators compare numeric values for relationships
such as equality. They are written using
*relational operators*.

All of Octave's comparison operators return a value of 1 if the comparison is true, or 0 if it is false. For matrix values, they all work on an element-by-element basis. For example,

[1, 2; 3, 4] == [1, 3; 2, 4] => 1 0 0 1

If one operand is a scalar and the other is a matrix, the scalar is compared to each element of the matrix in turn, and the result is the same size as the matrix.

`x``<`

`y`- True if
`x`is less than`y`. `x``<=`

`y`- True if
`x`is less than or equal to`y`. `x``==`

`y`- True if
`x`is equal to`y`. `x``>=`

`y`- True if
`x`is greater than or equal to`y`. `x``>`

`y`- True if
`x`is greater than`y`. `x``!=`

`y``x``~=`

`y``x``<>`

`y`- True if
`x`is not equal to`y`.

String comparisons may also be performed with the `strcmp`

function, not with the comparison operators listed above.
