This question might be closed as it sounds vague but I’m really asking this because I have no idea or my math background is not sufficient enough.
I’m trying to implement a challenge and a part of the challenge requires me to compute min and max values of a matrix. I have no trouble with matrix implementations and its operations however what is the min and max values of a matrix? Considering a 3×3 matrix is the min the smallest number among 9 numbers and max is the greatest or something else?
It really depends. The maximum could be the maximum entry, or the entry with the maximum absolute value or it could be the row (col) vector that is largest with respect to some norm.
