mindspore.Tensor.erfc

Tensor.erfc() → Tensor

Computes the complementary error function of self element-wise.

\[erfc(x) = 1 - \frac{2} {\sqrt{\pi}} \int\limits_0^{x} e^{-t^{2}} dt\]

Note

The input tensor self of the complementary error function, \(x\) in the above formula. Supported dtypes:

  • Ascend: float16, float32, float64, int64, bool, bfloat16.

  • GPU/CPU: float16, float32, float64.

Returns

Tensor. The dtype of output is float32 when dtype of self is in [bool, int64]. Otherwise output has the same dtype as the self.

Raises

  • TypeError – If self is not a Tensor.

  • TypeError –

    If dtype of self is not the following:

    • Ascend: float16, float32, float64, int64, bool, bfloat16.

    • GPU/CPU: float16, float32, float64.

Supported Platforms:

Ascend GPU CPU

>>> import mindspore
>>> import numpy as np
>>> from mindspore import Tensor
>>> input = Tensor(np.array([-1, 0, 1, 2, 3]), mindspore.float32)
>>> output = input.erfc()
