Hi everyone,
I'm just getting started with Cython, and I'm wondering whether fast
matrix and vector operations are currently supported. The two threads
linked below ("access to numpy functions?" and "numpy calls without
Python overhead?") suggest that such operations cannot be accelerated,
but I'm curious whether that has changed.
I work in computer vision with algorithms that frequently require
matrix multiplications, vector norm computations, manipulation of
individual rows of a matrix of feature vectors, and so forth. It would
be tremendously useful to be able to combine fast loops with these
operations! If Cython isn't going in this direction, could you kindly
suggest how I could interact with the relevant BLAS routines correctly
and efficiently from C?
Thanks,
Zak
