Re: GSL matrix transpose view

[Brian Gough <bjg at network-theory dot co dot uk>]

The GSL vector matrix model is designed to be compatible with BLAS,
which only supports a stride for the trailing dimension. That's a
design decision based on the fact that we're working to the existing
standards used by NAG, IMSL etc.

I just mention to the list that the GSL portable BLAS needs someone to
write the level 3 operations if anyone is interested in doing that.
