inserting vectors into a matrix

Hi,
I am wondering of there is a way that enables me to insert a column vector in a matrix (similar to insert column in excel) without replacing any existing column. For example I have Matrix "A" which is 4x4 and I want to insert a vector "B" to be the first column of "A" in order to obtain "A" 4x5 where the 1st column of "A" is vector "B"

And to insert a column in the middle part:
A = rand(4, 4);
B = rand(4, 1);
C(:, [1,2,5,3,4]) = [A, B];
Not nice, but it works. Alternatively:
C = [A(:, 1:2), B, A(:, 3:4)];
