Given a symbolic matrix product Csp=A*B^T for which a <A HREF="../Mat/MatTransposeColoring.html#MatTransposeColoring">MatTransposeColoring</A> context has been created and a dense matrix Cden=A*Btdense in which Btdens is obtained from <A HREF="../Mat/MatTransColoringApplySpToDen.html#MatTransColoringApplySpToDen">MatTransColoringApplySpToDen</A>(), recover sparse matrix Csp from Cden.
