For example, I have two column data:  
A = [1;2;3];  
B = [5;6;7];

In order to make a matrix with the first column being A and 2nd Column being B, I would do this in Matlab:  
C = [A, B];

But it does it the wrong way and I got the below matrix instead:  
[1, 2, 3]  
[4, 5, 6]

How do I do this simple task?

Many thanks.

You want `[A B]`, without the comma.
