mindspore.mint.sinc

mindspore.mint.sinc(input)

Computes the normalized sinc of input.

\[\begin{split}out_i = \begin{cases} \frac{sin(\pi input_i)}{\pi input_i} & input_i\neq 0\\ 1 & input_i=0 \end{cases}\end{split}\]

Parameters

input (Tensor) – The input Tensor.

Returns

Tensor, has the same shape as the input. The dtype of output is float32 when dtype of input is in [int, bool]. Otherwise output has the same dtype as the input.

Raises

TypeError – If input is not a Tensor.

Supported Platforms:

Ascend

Examples

>>> import mindspore
>>> import numpy as np
>>> from mindspore import Tensor, mint
>>> input = Tensor(np.array([0.62, 0.28, 0.43, 0.62]), mindspore.float32)
>>> output = mint.sinc(input)
>>> print(output)
