mindspore.ops.Erf

class mindspore.ops.Erf(*args, **kwargs)[source]

Computes the Gauss error function of x element-wise.

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

Inputs:

x (Tensor) - The input tensor. The data type must be float16 or float32.

Outputs:

Tensor, has the same shape and 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)
>>> erf = ops.Erf()
>>> output = erf(x)
>>> print(output)
