Extended-maxima of an Array

Hello everyone, I have an array 'A1' that has 21 rows and 6 columns. I want to find the Extended-maxima of each column using the matlab imextendedmax function.

I don't know what is wrong with my code!

for x = 1:6
A1_Colm = imextendedmax(A1(:,x), 1) %Extended-maxima with 1  H-maxima transform

M (21,6) = A1_Colm1; % to save the results from each loop in a new array M

end

The following error appears Subscripted assignment dimension mismatch.

Any help will be highly appreciated.

imexendedmax() returns an array the same size as its first input, A1(:,x) in this case. You are then trying to store that entire array into a single location, M(21,6).

I suspect that what you want is:

M(:,x) = A1_Colm1;
