[−][src]Struct ndarray_einsum_beta::contractors::pair_contractors::MatrixScalarProductGeneral
Permutes the axes of the LHS tensor to the output order and multiply all elements by the single scalar in the 0-d RHS tensor.
This contraction can arise when the simplification of the RHS tensor results in all the
axes being summed before the two tensors are contracted. For example, in the contraction
ij,k->ji
, the output matrix is equal to the LHS matrix, transposed and then scalar-multiplied
by the sum of the elements of the RHS tensor.
