Acosh

Versioned name : Acosh-3

Category : Arithmetic unary

Short description : Acosh performs element-wise hyperbolic inverse cosine (arccosh) operation with given tensor.

Detailed description : Operation takes one input tensor and performs the element-wise hyperbolic inverse cosine operation on a given input tensor, based on the following mathematical formula:

\[a_{i} = acosh(a_{i})\]

Attributes : Acosh operation has no attributes.

Inputs

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

Outputs

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

Types

• T : any numeric type.
