How do I compare two similar sized matrices?

Hi all!
I have two 76x2000 matrices and I would like to compare them to see which one is always higher. What is the best way for me to go about this? A function that would allow me to put in different pairs would be most appreciated.
Thank you!

"what do you mean by a 76x2000 logical array"   there is a good answer in the middle of Introducing MATLAB Fundamental Classes (Data Types)
I still don't fully understand what you mean by "matrices have a higher value". The example you provided above explains "higher" regarding scalars, not matrices. Please give a small example regarding matrices. See Norm (mathematics) and Vector and matrix norms.

"every single value in that matrix [ A ] is higher than the corresponding one in the other matrix [ B ]"
is_gt = A > B;
is_higher = all( is_gt(:) );
(:) is a trick to reshape a matrix to a column vector.

Secondly, try
is_gt = mean(A,1,'omitnan') > mean(B,1,'omitnan');
is_higher = all( is_gt(:) );
