You will have to access the memory directly for that access pattern. The
gsl_matrix type is designed so that it can always be passed to a BLAS

Well, then I suppose that will have to do. If unit stride is good
enough for BLAS, it will be good enough for me too. :-) If I really
need that Octave-like syntax, I can copy matrices within my C++
classes, which is what I was trying to avoid.

The implementation allows views of both const and non-const objects
without casting.
Thank you (again) for the explanations!
