mindspore.ops.csr_cosh

mindspore.ops.csr_cosh(x: CSRTensor)[source]

Computes hyperbolic cosine of input element-wise.

\[out_i = \cosh(x_i)\]

Parameters

x (CSRTensor) – The input CSRTensor of hyperbolic cosine function, its data type must be float16, float32, float64, complex64 or complex128.

Returns

CSRTensor, has the same shape as x.

Raises

TypeError – If the dtype of x is not one of the following types: float16, float32, float64, complex64, complex128.
TypeError – If x is not a CSRTensor.

Supported Platforms:: Ascend GPU CPU

Examples

>>> from mindspore import dtype as mstype
>>> from mindspore import Tensor, ops, CSRTensor
>>> indptr = Tensor([0, 1, 2, 2], dtype=mstype.int32)
>>> indices = Tensor([3, 0], dtype=mstype.int32)
>>> values = Tensor([-1, 2], dtype=mstype.float32)
>>> shape = (3, 4)
>>> x = CSRTensor(indptr, indices, values, shape)
>>> output = ops.csr_cosh(x)
>>> print(output.values)
