Hi,
following the excellent advice of V. Armando Sole, I have finally succeeded in
calling the blas routines shipped with scipy from cython.
I am doing this to avoid shipping an extra blas library for some project of
mine that uses scipy but has some things coded in cython for extra speed.
So
Hello,
i know that the array object is already crowded, but i would like
to see the abs method added, especially doing work on the console.
Considering that many much less used functions are also implemented
as a method, i don't think adding one more would be problematic.
greetings

... and it is not deterministic too...
About 1 time over 6 the code calling the scipy blas gives a completely wrong
result. How can this be?

Partially fixed.
I was messing the row, column order. For some reason this was working in some
case. Now I've fixed it and it *always* works.
However, it is still slower than the cblas
cblas - 0.69 sec
scipy blas - 0.74 sec
Any clue why?

if you are using scipy blas, the real question is which blas is underneath ?
OpenBlas, GotoBlas, Atlas, MKL ?
Under
