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.

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 \(a-n \ge 0\).
