I have a matrix like
1 3 4
1 2 6
1 1 5
1 4 3
What I would like to do is to, for each row, take a max of column 2 and column 3. That is, the output will be like
1 3 4 4
1 2 6 6
1 1 5 5
1 4 3 4
I would like to know whether it is possible to do this calculation without writing a loop.

Did you take up the MATLAB On-ramp course? You seem to be asking the basic questions over and over again?

I know how to write a loop. I jjust wanted to understand whether there is a better way than loop. Having said that I will work on it.

A(:,4)=max(A(:,2:3),[],2);
