How to store two signal inputs into a matrix or vector?

I have a system input and output, u(k-1) and y(k-1) and I wish to have them in the form [u(k-1);y(k-1)] To allow me to do matrix math on them. I was wondering if this were possible in simulink?

Please help.

Thanks again, I just realized this a second ago. Tryin to implement adaptive control.
