binning data in python with scipy/numpy

August 19, 2022 by Magenaut

is there a more efficient way to take an average of an array in prespecified bins? for example, i have an array of numbers and an array corresponding to bin start and end positions in that array, and I want to just take the mean in those bins? I have code that does it below but i am wondering how it can be cut down and improved. thanks.

Interactive large plot with ~20 million sample points and gigabytes of data

August 16, 2022 by Magenaut

I have got a problem (with my RAM) here: it’s not able to hold the data I want to plot. I do have sufficient HD space. Is there any solution to avoid that “shadowing” of my data-set?

multithreaded blas in python/numpy

August 16, 2022 by Magenaut

I am trying to implement a large number of matrix-matrix multiplications in Python. Initially, I assumed that NumPy would use automatically my threaded BLAS libraries since I built it against those libraries. However, when I look at top or something else it seems like the code does not use threading at all.
