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.
