Struct ndarray_einsum_beta::contractors::pair_contractors::MatrixScalarProduct

pub struct MatrixScalarProduct {}

Multiplies every element of the LHS tensor by the single scalar in the 0-d RHS tensor.

This contraction can arise when the simplification of the LHS tensor results in all the axes being summed before the two tensors are contracted. For example, in the contraction ij,k->ij, every element of the LHS tensor is simply multiplied by the sum of the elements of the RHS tensor.
