Sure, you can store a triangular matrix
in a single array.  Now write a procedure
for multiplying two of them.

Really simple and transparent, right (or wrong)?

I should  have put in the stuff below in my previous message;
I was thinking of triangular matrices, where you save memory
by  having the rows of different lengths.
    

It's probably more efficient to store it in a single array similar
to the link below (quick Google search) than allocating each row
individually.

But please tell me, have you _ever_ used 3-D arrays?  4-D arrays?
    

Yes. Yes.
