How can I make a vector in matlab, like vec(x)?

Hello all,
I am trying to replicate this formula:
I am doing so as follows:
Theta = A*B-C;
vTheta = vec(Theta');
A, B en C are defined. The problem is that Matlab does not seem to know the function 'vec' to do what I would like to do with Theta as in the formula...
How can I fix this?
Thanks in advance!

"Does not seem" or do you get a real error message? If Matlab does not have such a function, you can fix this by writing it.
Sorry for this trivial answer, but the provided details do not allow to give a more specific one.

I wrote a vec function in grad school for exactly this use. Here it is, authored almost exactly 7 years ago apparently!
attached.

Suppose you have a matrix X. You can obtain a vec(X) simply by the following:
vecX = X(:);
