MATLAB: How to get maximum value of the matrix

MATLABmax min matlab

I have a matrix which is 256*256. It has double value in it. May I ask how to get the maximum and minimum value in this matrix?

Thank you so much!

Starting in R2018b, you can use the following command to find the maximum over all elements in an array A:

M = max(A, [], 'all');

For previous releases, use:

M = max(A(:));

out = min(A(A~=0))
