Nobody has stated Ruby is fast. Your argument, however, is: "my algorithm is 
bigger than your algorithm".

Trivially put your matrices into a C++ library, bond it to Ruby, and keep 
going.

Programming is mostly about command-and-control code, glueing ready-made 
libraries together. The faster and easier the glueing is, the more time you 
have open to optimize the few things that need it.

If they are fast, leave them there.
