let's say , I have matrix
A=[3 1;4 9 ;5 7 ];
A=[3 1
4 9
5 7 ];
I can find the maximum value from matrix A is 9:
max_value=max(max(A));
How can I get the value is in same row of 9, that is, 4 ?

[Val,ix]=max(A(:));
[r,~]=ind2sub(size(A),ix);
A(r,:) %complete row where maximum exists

>> A = [3,1;4,9;5,7]
A =
3 1
4 9
5 7
>> [V,X] = max(A(:));
>> [R,C] = ind2sub(size(A),X);
>> A(R,3-C)
ans = 4

[Val,ix]=max(A(:));
[r,c]=ind2sub(size(A),ix);
Wanted = A(r,setdiff(1:size(A,2),c))

What’s the hurry before editing the comment?? XD . I was using my mobile to answer and I just mistyped the colon inside setdiff().
