Hi, I am trying to convert a coordinate_matrix to a compressed_matrix using the "assign" function and got weird compilations errors. Could you please help me with what the problem is.I am running the following code:------------------int size=10;typedef ublas::coordinate_matrix<double> data_type_1;typedef ublas::compressed_matrix<double> data_type;
data_type_1 A(size,size, 9*size);data_type M;M.resize(A.size1(),A.size2(),A.nnz()); // Convert matrix A into a compressed one.M.assign(A);       // <----------- Error occurs here!-------------------------
I get the following compilation errors:

Your help is really appreciated. Thanks a lot!
