I want to extract a row from a matrix for which the last column element is largest. for example if my matrix is
1 2 3
1 1 4
2 1 2
3 2 5
my answer would be the last row 3 2 5 because 5 is the largest element in the last column. How do I do this please help.

M = [1,2,3;1,1,4;2,1,2;3,2,5];
[~, max_idx] = max( M(:,end) );
max_row = M(max_idx,:);

I think I solved it, if my matrix is A
[C,I]=max(A(:,3)) %it will find the max in the last column and its index
row=A(I,:)
