mindspore.ops.expm1

mindspore.ops.expm1(input)[source]

Returns exponential then minus 1 of a tensor element-wise.

\[out_i = e^{x_i} - 1\]

Parameters: input (Tensor) – The input Tensor. \(x\) in the above formula.
Returns: Tensor, has the same shape as the input.
Raises: TypeError – If input is not a Tensor.

Supported Platforms:: Ascend GPU CPU

Examples

>>> import mindspore
>>> import numpy as np
>>> from mindspore import Tensor, ops
>>> x = Tensor(np.array([0.0, 1.0, 2.0, 4.0]), mindspore.float32)
>>> output = ops.expm1(x)
>>> print(output)
