Perfplot to compare performance of several functions with multiple arguments (more than one)
I would like to show performance of some functions by perfplot that uses more than one arguments, but I don't know how could I do this (I'm not familiar much with perfplot). One said broadcast all args to just x, but I am confused yet how to use it.…

Why `vectorize` is outperformed by `frompyfunc`?
Numpy offers vectorize and frompyfunc with similar functionalies.
As pointed out in this SO-post, vectorize wraps frompyfunc and handles the type of the returned array correctly, while frompyfunc returns an array of np.object.
However, frompyfunc…

How to add measured input values as x-axis labels in generated chart?
I'm using perfplot to make only a few measurements. I would like to see measured input values as x-axis labels similarly to generated y-axis labels.
Currently I see 10^2 10^3 10^4 10^5 10^6 10^7 as x-axis labels.
I want to have 16 512 16384 …
