Fast histogramming in python built on pybind11
Project description
pygram11
Simple and fast histogramming in python via pybind11 and (optionally) OpenMP
pygram11 provides fast functions for generating histograms (and
their sums-of-weights squared). Fixed and variable width binned
histograms are supported. The API is very simple, check out the
documentation.
Installing
pygram11 requires only NumPy and pybind11 (and therefore a C++ compiler with C++11 support).
From PyPI
$ pip install pygram11
From Source
$ git clone https://github.com/drdavis/pygram11.git
$ cd pygram11
$ pip install .
In Action
A fixed bin width histogram of weighted data in one dimension, accelerated with OpenMP:
>>> x = np.random.randn(10000)
>>> w = np.random.uniform(0.8, 1.2, 10000)
>>> h, sw2 = pygram11.histogram(x, bins=40, range=(-4, 4), weights=w, omp=True)
>>> stat_err = np.sqrt(sw2)
A variable bin width histogram in two dimensions:
>>> x = np.random.randn(10000)
>>> y = np.random.randn(10000)
>>> xbins = [-2.0, -1.0, -0.5, 1.5, 2.0]
>>> ybins = [-3.0, -1.5, -0.1, 0.8, 2.0]
>>> h = pygram11.histogram2d(x, y, bins=[xbins, ybins])
