- mars.tensor.special.erfinv(x, out=None, where=None, **kwargs)[source]#
Inverse of the error function.
Computes the inverse of the error function.
In the complex domain, there is no unique complex number w satisfying erf(w)=z. This indicates a true inverse function would have multi-value. When the domain restricts to the real, -1 < x < 1, there is a unique real number satisfying erf(erfinv(x)) = x.
- Parameters
y (ndarray) – Argument at which to evaluate. Domain: [-1, 1]
- Returns
erfinv – The inverse of erf of y, element-wise)
- Return type
ndarray
