Products of sparse by dense matrices dont revert to specialized methods
using LinearAlgebra function multiply_sparse_dense(A::SparseMatrixCSC{T}, B::AbstractMatrix{T}) where T m, n = size(A) C = zeros(T, m, size(B, 2)) for j = 1:size(B, 2) for i = 1:n for k = A.colptr[i]:(A.colptr[i+1]-1) C[A.rowval[k], j]
