[Numpy-discussion] Calling BLAS functions from Python

2019-08-27 Thread Jens Jørgen Mortensen
Hi! I'm trying to use dgemm, zgemm and friends from scipy.linalg.blas to multiply matrices efficiently. As an example, I'd like to do: c += a.dot(b) using whatever BLAS scipy is linked to and I want to avoid copies of large matrices. This works the way I want it: >>> import numpy as

Hi all, At https://github.com/numpy/numpy.org/issues/37 we have an update to the NumPy logo, changing the colors for more contrast / a more modern look. Please have a look! What would also be helpful is to know who made this logo, and with what tool. We'd like to produce a new SVG, but doing

The inplace overwriting is done if f2py can forward the original array down to the low level. When it is not contiguous then it has to somehow marshall the view into a compatible array and that is when the inbetween array is formed. And also that array can also be overwritten but that would not
