- mars.tensor.special.gammainccinv(a, b, **kwargs)[源代码]¶
Inverse of the upper incomplete gamma function with respect to x
Given an input \(y\) between 0 and 1, returns \(x\) such that \(y = Q(a, x)\). Here \(Q\) is the upper incomplete gamma function; see gammaincc. This is well-defined because the upper incomplete gamma function is monotonic as can be seen from its definition in [dlmf].
- 参数
a (array_like) – Positive parameter
