MatTransColoringApplyDenToSp#
Given a symbolic matrix product \(C_{sp} = A*B^T\) for which a MatTransposeColoring context has been created and a dense matrix \(C_{den} = A*B^T_{dense}\) in which B^T_{dens} is obtained from MatTransColoringApplySpToDen(), recover sparse matrix \(C_{sp}\) from \(C_{den}\).
