maxframe.tensor.special.rgamma

maxframe.tensor.special.rgamma(z, out=None)

Reciprocal of the gamma function.

Defined as \(1 / \Gamma(z)\), where \(\Gamma\) is the gamma function. For more on the gamma function see gamma.

Parameters:

• z (array_like) – Real or complex valued input

• out (ndarray, optional) – Optional output array for the function results

Returns:

Function results

Return type:

scalar or ndarray

See also

gamma, gammaln, loggamma

Notes

The gamma function has no zeros and has simple poles at nonpositive integers, so rgamma is an entire function with zeros at the nonpositive integers. See the discussion in [dlmf] for more details.
