(GT) Greater than relation for handles. H1 > H2 performs element-wise comparisons between handle arrays H1 and H2. H1 and H2 must be of the same dimensions unless one is a scalar.
The result is a logical array of the same dimensions, where each element is an element-wise > result.

If one of H1 or H2 is scalar, scalar expansion is performed and the result will match the dimensions of the array that is not scalar.

TF = GT(H1, H2) stores the result in a logical array of the same dimensions.
