How can I find multiple maximum values and they are indexes of 4-D array

Hi every body, pleas who can help me to find the multiple values and they indexes of 4-D array ?

as an example below :

A(:,:,1,1)= 

            1  3  5
            3  5  1
            5  1  3

I want the output as :

 max value= 5 , index (3,1,1,1) 
 max value= 5 , index (2,2,1,1) 
 max value= 5 , index (1,3,1,1)

My attempt to solve that is :

 [max_val, Index] = max(A(:));
 [A1,A2,A3,A4] = ind2sub(size(A),Index);

the output was:

 max value= 5 , index =3
 A1= 3
 A2= 1
 A3= 1
 A4= 1

Which means only the first maximum value, but I want all values. Thank you in advance

Hi,

You can try something like this:

maxval = max(A(:));
idx = find(A == maxval);
[A1,A2,A3,A4] = ind2sub(size(A),idx);

This should give all the max value indices.

Thanks for your help, it is good solution.
