[Getfem-users] use of gmm::col_matrix< gmm::wsvector<double> > for assembly operation

[mikael gueguen]

hello

i use the type gmm::col_matrix< gmm::wsvector<double> > matrix for  
assembly operation.
This is my global matrix, and i use a dynamic array  for elementary  
operation
(i interface a fortran subroutine with my c++ code).
for a problem with six hundred finite elements (the size of global  
matrix is 12000x12000),
i notice that the access time  increase strongly during the assembly.
is it normal?

best regards.
