want to caompare element by element martix operators and any one element or all element in A if > B should return matrix A as greater .

Here first column of A is greater compared to B .

Here while comparing A and B . Even if one element in A if greater B should return Marix A as greater

You can use inequalities straight away.

idx = A>B ;
