|
**Versioned name**: *Cos-1*
|
|
|
|
**Category**: *Arithmetic unary*
|
|
|
|
**Short description**: *Cos* performs element-wise cosine operation on a given input tensor.
|
|
|
|
**Detailed description**: *Cos* performs element-wise cosine operation on a given input tensor, based on the following mathematical formula:
|
|
|
|
\f[
|
|
a_{i} = cos(a_{i})
|
|
\f]
|
|
|
|
**Attributes**: *Cos* operation has no attributes.
|
|
|
|
