How to do max value

Hi, can you help me ? I have y1, y2, y3, y4 and y5. All of them are 2x70 double. And I need to find max y from them.

[Kaushik Lakshminarasimhan]

You have five matrices. Can you clarify what you mean by max y? Do you want to find the maximum element in each of the five matrices?

[OCDER]

To add on, do you want to find the maximum per row or col or overall?

A = [1 2; 3 4];
max(A, 1)  % 3,4
max(A, 2)  % 2;4
max(A(:))  % 4
