I have a matrix A=rand(7,25)
I want to find the second largest/third largest/fourth/fifth and sixth largest value among all the columns of matrix "A". No need of seventh largest as there are total 7 values in each column.
Thank you.

A=rand(7,25)
[aa,indices]=sort(A,'descend')

They're all in indices. Why do you need different arrays??? If you do, just do
maxIndexes = indices(1,:);
max2Indexes = indices(2,:);
max3Indexes = indices(3,:);
and so on.

Thanks very much. This is a good one - it gives correct indices of the original array for any max
