mindspore.ops.igammac

mindspore.ops.igammac(input, other)[source]

Calculates upper regularized incomplete Gamma function.

If we define input as a and other as x, the upper regularized incomplete Gamma function is defined as:

\[Q(a, x) = Gamma(a, x) / Gamma(a) = 1 - P(a, x)\]

where

\[Gamma(a, x) = \int_{x}^{\infty} t^{a-1} exp(-t) dt\]

is the upper incomplete Gama function.

Above \(P(a, x)\) is the lower regularized incomplete Gamma function.

>>> other = mindspore.tensor([2.0, 3.0, 4.0, 5.0])
>>> output = mindspore.ops.igammac(input, other)
>>> print(output)
