name_of_system.matrix->print(); should do the trick. Have a look at sparse_matrix.h for more details. - Dave yunfei zhu wrote: > Hi, > when we add elemenet matrix into the global matrix by stament like: > name_of_system.matrix->add_matrix(Ke, dof_indices); > If I want to print out the global mat

[Libmesh-users] access global matrix

2008-09-08 Thread yunfei zhu
Hi, when we add elemenet matrix into the global matrix by stament like: name_of_system.matrix->add_matrix(Ke, dof_indices); If I want to print out the global matrix, how should I achieve that? Is there some function like print() to do that? Thank you very much. Regards, yunfei
