Combination with ordinary arrays

Hello, matlisp-team (and/or other users).

First, I would like to say that matlisp helps me quite a lot.  Thank
you.  Next, I have the following question: how does one do the
interaction with usual arrays in the best way.  E.g., is it possible
to have matlisp matrices operating as linear operators on ordinary
uniform double-float vectors?  Or is it necessary to construct matlisp
nx1-matrices for those vectors instead?  What do you recommend?

Yours, Nicolas.
