m=randi(200,4) % sample data
m =
125 95 46 63
118 47 35 185
42 169 46 87
61 39 88 37
The engine:
[~,v]=max(m);
yields
>> v =
1 3 4 2
>>
ADDENDUM:
Ok, latest guess as I thought prior was unlikely...let me try one more time to see if follow...
[~,ix]=max(m(:)); % index of overall maximum in matrix m
[r,c]=ind2sub(size(m),ix); % convert index to row,column location in m
v=m(r,:) % row of m corresponding to that location
result for above sample m is:
>> v =
118 47 35 185
>>
That what you looking for?
