Struct ScalarMatrixProductGeneral 

pub struct ScalarMatrixProductGeneral {
    rhs_permutation: Permutation,
    scalar_matrix_product: ScalarMatrixProduct,
}

Permutes the axes of the RHS tensor to the output order and multiply all elements 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->kj, the output matrix is equal to the RHS matrix, transposed and then scalar-multiplied by the sum of the elements of the LHS tensor.

Fields

rhs_permutation: Permutation

scalar_matrix_product: ScalarMatrixProduct
