erfinv

paddle. erfinv ( x, name=None ) [source]

The inverse error function of x, .

Equation:
\[erfinv(erf(x)) = x.\]
Parameters
  • x (Tensor) – An N-D Tensor, the data type is float32, float64.

  • name (str, optional) – Name for the operation (optional, default is None). For more information, please refer to Name.

Returns

An N-D Tensor, the shape and data type is the same with input.

Return type

out (Tensor)

Example

import paddle

x = paddle.to_tensor([0, 0.5, -1.], dtype="float32")
out = paddle.erfinv(x)
# out: [0, 0.4769, -inf]
