mindspore.ops.coo_cosh

mindspore.ops.coo_cosh(x: COOTensor)

Computes hyperbolic cosine of input element-wise.

$$ou{t}_i=\cosh (x_i)$$

Parameters

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

Returns

COOTensor, 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 COOTensor.

Supported Platforms:

Ascend GPU CPU

Examples

>>> from mindspore import dtype as mstype
>>> from mindspore import Tensor, ops, COOTensor
>>> indices = Tensor([[0, 1], [1, 2]], dtype=mstype.int64)
>>> values = Tensor([-1, 2], dtype=mstype.float32)
>>> shape = (3, 4)
>>> x = COOTensor(indices, values, shape)
>>> output = ops.coo_cosh(x)
>>> print(output.values)
