Struct ScalarMatrixProduct 

pub struct ScalarMatrixProduct {}

Multiplies every element of the RHS tensor by the single scalar in the 0-d LHS 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 i,jk->jk, every element of the RHS tensor is simply multiplied by the sum of the elements of the LHS tensor.
