How to find location of a matrix array by array.

A = [1 4 5 2 6 8 5 4;

2 5 3 5 9 2 4 5;

3 2 6 4 2 4 5 3];

Amax = max(A');

lo = find(A==Amax');

then I got [9; 14; 16;] for their positions. What do I have to do if I want their positions to be on each array? I want lo to be [6; 5; 3].

Hi Ratchanon,

This page describes that find function is able to ouput the row and column indices if you set two output arguments.

Here is an example.

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

Amax = max(A');

[row, column] = find(A==Amax');

I hope this helps you.

Thank you,

Johnny
