Usually the way this kind of thing is handled is by adding an
np.ma.his

Right now it looks like there's no histogram function at all
Hope this isn't too off-topic: but it would be very nice if np.histogram
and np.histogram2d supported masked arrays. Is this out of scope for
outside the numpy.ma package?

Hi,
It sounds like putting together a PR makes sense then. I'll try hacking on
this a bit.

I need to do both unweighted & weighted histograms and we got a factor 5 using
(simple) cython:
it is i

Dispatching to a different method seems lik
My apologies for the typo: 'implements' -> 'implementations'

It might make sense to dispatch to difference c implements if the bins are
equally spaced (as created by using an integer for the np.histogram bins
argument), vs. non-equally-spaced bins.
In that case, getting the bigger speedup may be easier, at least for one
common use case.

Hi,
Numpy.histogram is implemented in python, and is a little sluggish. This
has been discussed previously on the mailing list, [1, 2]. It came up in a
project that I maintain, where a new feature is bottlenecked by
numpy.histogram, and one developer suggested a faster implementation in
cython [3]
