TensorMath

trait TensorMath[T] extends AnyRef

It provides multiple math operation functions for manipulating Tensor objects. All functions support both allocating a new Tensor to return the result and treating the caller as a target Tensor, in which case the target Tensor(s) will be resized accordingly and filled with the result. This property is especially useful when one wants to have tight control over when memory is allocated.

T

should be double or float
