You have two variables u, v and you calculate the shape using the size command:
>> size(u) ans = 1 3 >> size(v) ans = 3 1 I want a matrix with 3 columns, the vectors u and v in the first two, and their sum in the third.

This should do the trick using the ' for transpose
new_matrix = [u', v', (u+v)']

@Meenakshi S: Please do not let us guess. Does "not accept" means, that you get an error message? If so, please post it here. It is much easier to fix an error than to guess, what the error is.
Many readers of the forum are not native English speakers. Then kewl abbrevs makes it harder to read your messages.

There are a few ways to do this, for example:
x = [u' v (u' + v)]
The apostrophe can be used to transpose a matrix. You could also use the 'reshape' command.

This is a correct answer. Because I assume, that this is a homework question, I recommend not to post the solution, because then the OP cannot submit this as his solution anymore. It is better to ask, what she has tried so far and which problems occur.
