Multi-thread matrix scaling

Marco Caliari-4
Hi,

while looking at

https://savannah.gnu.org/bugs/?54005

I discovered that scaling a matrix is single-thread in octave, while
multi-thread in matlab. Would it be possible to use the BLAS routine Xscal
which, in openblas for instance, is multi-thread? How complicate would be such
a change?

Regards,

Marco
