[maxvals, maxidx] = max(YourMatrix, [], 2);
Now maxidx will be a vector of column numbers, one per row.

And think u again
[maxvals, maxidx] = max(YourMatrix, [], 2);

The 2 refers to dimension #2, the columns . The above functions equivalently to
for K = 1 : size(YourMatrix,1)
[maxvals(K,1), maxidx(K,1)] = max(YourMatrix(K,:),[]);
end
If you left out the 2, then the default would be to work along the first non-singular dimension, like
for K = 1 : size(YourMatrix,2)
[maxvals(1,K), maxidx(1,K)] = max(YourMatrix(:,K),[]);
end
