How do you do a Matrix on this calculator?

The CA 756 doesn't really have any matrix capabilities. If you're looking for a keystroke method for inverting a matrix or finding its determinant, for example, this calculator won't do it. The closest the CA 756 comes is allowing you to use a series of memory registers as a vector (one-dimensional array).

That probably wasn't the answer you wanted to see, but there it is.
