if I have
A=[25,41,38] when I sort this matrix by descending order , I will get A=[41,38,21]
I want to arrange indices of matrix A by descending order and shows a result (B) like this
B=[2,3,1]
How to create program to get this result ?
Thanks in advance.

To get ‘B’, ask for the second output from sort:
A=[25,41,38];
[A_sorted,B] = sort(A, 'descend')
A_sorted =
41 38 25
B =
2 3 1
