mindspore.ops.Erfc

class mindspore.ops.Erfc

Computes the complementary error function of x element-wise.

$$erfc(x)=1-\frac{2}{\sqrt{\pi }}\underset{0}{\overset{x}{\int }}{e}^{-t^2}dt$$

Inputs:

• x (Tensor) - The input tensor. The data type must be float16 or float32. $(N,\ast )$ where $\ast$ means, any number of additional dimensions, its rank should less than 8.

Outputs:

Tensor, has the same shap dtype as the x.

Raises

TypeError – If dtype of x is neither float16 nor float32.

Supported Platforms:

Ascend GPU

Examples

>>> x = Tensor(np.array([-1, 0, 1, 2, 3]), mindspore.float32)
>>> erfc = ops.Erfc()
>>> output = erfc(x)
>>> print(output)
