It seems to be a fact that numerically intensive code spends a lot of time
performing matrix maths. If this means `array performance' is the limiting
factor in performance why it it `tunnel vision' to concentrate on it?

There are, of course, the usual caveats:

* For some users the problem is with coding and building cycles rather
  than raw performance.

* Are people just using matrix maths for historic reasons?
   IMHO probably not.
