Reshaping a square matrix to a vector

Hi, I need to convert a 10 by 10 matrix into a 100 by 1 matrix by concatenating each column to the bottom of the preceding one. For example:
1 2 3 4
5 6 7 8
9 10 11 12
13 14 15 16
into [1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16]'
I've tried using reshape but I'm not getting what I want... moreover, I'm trying to use a for loop but can't seem to get it right.
Any help is much appreciated.
Thanks!

This matches your words:
A = rand(10,10);
B = A(:); % one way
B = reshape(A,100,1); % another way
This matches your example:
B = reshape(A.',100,1);
