Cosh

• Domain: ai.onnx

• Since version: 22

Computes the Cosh value of the input tensor element-wise.

Inputs

• input (T): Input tensor

Outputs

• output (T): The hyperbolic cosine values of the input tensor computed element-wise

Type Constraints

• T: Constrain input and output types to float tensors. Allowed types: tensor(bfloat16), tensor(double), tensor(float), tensor(float16).
