MATLAB: How to find second largest OR third largest Or any largest value among the columns of a matrix

Question

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.

Answer 1

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