mindspore.ops.erfinv

mindspore.ops.erfinv(input)[source]

Returns the result of the inverse error function with input, which is defined in the range (-1, 1) as:

\[erfinv(erf(x)) = x\]

where \(x\) is the input.

Parameters: input (Tensor) – The input tensor to compute with, with data type float16, float32 or float64.
Returns: Tensor, has the same shape and dtype as input.
Raises: TypeError – If dtype of input is not float16, float32 or float64.

Supported Platforms:: Ascend GPU CPU

Examples

>>> import mindspore
>>> import numpy as np
>>> from mindspore import Tensor, ops
>>> x = Tensor(np.array([0, 0.5, -0.9]), mindspore.float32)
>>> output = ops.erfinv(x)
>>> print(output)
[ 0.          0.47695306 -1.1630805 ]
