Detailed Description

template<typename Subtype, int ExprRank, typename... Children>
struct sp::TensorTensorOp< Subtype, ExprRank, Children >

Base class for any TensorOp that has only TensorLikes as children.

This provides some boilerplate-saving defaults for a few things, but is otherwise identical to TensorOp.

When implementing a new operator, you'll want to extend either this, EltwiseTensorOp (if your operator is an element-wise function of TensorLikes), or TensorOp (if your operator has non-TensorLike children, or is otherwise just a bit insane).

See also: EltwiseTensorOp; TensorOp

Template Parameters
