skypy.utils.special.gammaincc

skypy.utils.special.gammaincc(a, x)[source] [edit on github]

Regularized upper incomplete gamma function.

This implementation of gammaincc allows \(a\) real and \(x\) nonnegative.

Parameters
aarray_like

Real parameter.

xarray_like

Nonnegative argument.

Returns
scalar or ndarray

Values of the upper incomplete gamma function.

scipy.special.gammaincc

Computes the start of the recurrence.

Notes

The function value is computed via a recurrence from the value of scipy.special.gammaincc for arguments \(a-n, x\) where \(n\) is the smallest integer such that \(a-n \ge 0\).
