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.
 < y <= y == y >= y > y != y ~= yString comparisons may also be performed with the strcmp
function, not with the comparison operators listed above.
