 a=[4 5 6 7;2 3 1 4;6 7 8 5;9 5 6 4]

i want to know index of max of each column between 1 and 3 rows..

>>a

4 5 6 7
2 3 4 4
6 7 8 5
9 5 6 4

max rows 1:3 is:
4 5 6==>6  =>index 3
2 3 1==>3 => index 2
6 7 8==>8=> index 3
9 5 6==>9==> index 1


answer is : 3 2 3 1


i try it :

[e,g]=find( a(1:3)==max(a(1:3,:)),3-1,"first")
