MATLAB: How to find index of first 3 maximum number in matrix

Question

I have the following function that n is the first 3 maximum value of matrix m:

m = [7;1;4;4;12;2;6;10;2];
temp = sort( m, 'descend' );
n = temp(1:3)

I need to know the index of matrix n, like:

p = [5;8;1]; % first max value in matrix m is 12 that it located in the fifth row

Answer 1

use the second output argument of sort

m = [7;1;4;4;12;2;6;10;2];
[temp,originalpos] = sort( m, 'descend' );
n = temp(1:3)
p=originalpos(1:3)
