Detailed Description

template<typename LHS, typename RHS>
struct sp::t::OuterProd< LHS, RHS >

Represents the Tensor formed by the outer product of two tensors.

When applied to two rank-1 Tensors, or Vectors, produces the matrix given by the first multiplied by the transpose of the second.

Lazily generates the elements on demand.
