You can add A, B into one variable using [A B] .

Do I need to type in C=[A B] manually? because I don't know the exact number of arrays I have

@Wei Nick Chan: you should put all of your arrays into one cell array, then the task of concatenating them together is trivial:

out = cat(2,C{:});

MATLAB can be really fast and simple, when the code is well designed. With lots of separate variables it will be slow and buggy code... read this to know why:
