Tutorial
from autograd import grad
from autograd_gamma import gammainc, gammaincc, gammaincln, gammainccln
grad(gammainc, argnum=0)(1., 2.)
grad(gammaincc, argnum=0)(1., 2.)
# logarithmic functions too.
grad(gammaincln, argnum=0)(1., 2.)
grad(gammainccln, argnum=0)(1., 2.)
from autograd_gamma import betainc, betaincln
grad(betainc, argnum=0)(1., 2., 0.5)
grad(betainc, argnum=1)(1., 2., 0.5)
# logarithmic functions too.
grad(betaincln, argnum=0)(1., 2., 0.5)
grad(betaincln, argnum=1)(1., 2., 0.5)
Long-term goal
Build and improve upon the derivative of the upper and lower incomplete gamma functions. Eventually, if we have a fast analytical solution, we will merge into the autograd library.
