Project description

PyPI-License PyPI-Version Anaconda-Version Anaconda-Downloads Badge Documentation Status

This package provides a python interface for the Cephes library. It also supports Numba and its nopython mode.

Usage

from ncephes import cprob
print(cprob.incbet(1., 3., 0.3))

prints 0.657.

You can also call them inside a numba function

from ncephes import cprob
from numba import jit

@jit
def numba_incbet(a, b, x):
    return cprob.incbet(a, b, x)

print(numba_incbet(1., 3., 0.3))

and with nopython mode and nogil enabled

from ncephes import cprob
from numba import jit

incbet = cprob.incbet

@jit(nogil=True, nopython=True)
def numba_incbet(a, b, x):
    return incbet(a, b, x)

print(numba_incbet(1., 3., 0.3))

One can also statically link the compiled Cephes libraries ncprob and ncellf. Please, have a peek at the examples/prj_name for a minimalistic example.
