Unary

The unary operator has a collection of basic unary calculation, like Absolute, trigonometric functions etc. An unary operator do element-wise calculation on each input tensor and store result in corresponding output tensor.

Few notes:

• The inputTensors and outputTensors should have same number of tensors.
• Corresponding input and output tensors should have same shapes.

All unary operators can be initialized:

let op = SomeUnaryOp()
