# Cosh¶

Versioned name : Cosh-1

Category : Arithmetic unary

Short description : Cosh performs element-wise hyperbolic cosine operation on a given input tensor.

Detailed description : Cosh performs element-wise hyperbolic cosine (cosh) operation on a given input tensor, based on the following mathematical formula:

$a_{i} = cosh(a_{i})$

Attributes : Cosh operation has no attributes.

Inputs

• 1 : A tensor of type T and arbitrary shape. Required.

Outputs

• 1 : The result of element-wise Cosh operation. A tensor of type T and the same shape as the input tensor.

Types
