Hi Hicham,
maybe you should follow the example on the documentation page concerning
gf_workspace :
http://download.gna.org/getfem/doc/getfem_matlab/gfm_18.html
Nevertheless, even with these instructions I have also some problems for
managing the memory used by getfem in matlab : I call an external
subroutine, which follows the advices of the documentation concerning
gf_workspace, but after several calls of the subroutine matlab finally
crashes.
Does someone experiment the same behavior?
Best regards,
Ronan

Hello,
I am using gf_asm(), from the Matlab interface, inside a loop. I realized that
the used memory increases with iterations until my program runs out of memory.
I would like to know if this is a bug or just something wrong with my program.
The example below illustrate my problem.
Thank you in advance.
Hicham

Omega = gf_mesh('triangles grid',[0:dx:1],[0:dx:1]);
Vh = gf_mesh_fem(Omega,1);
gf_mesh_fem_set(Vh,'fem',gf_fem('FEM_PK(2,1)'));
im = gf_mesh_im(Omega, gf_integ('IM_EXACT_SIMPLEX(2)')) ;
VhNdof=gf_mesh_fem_get(Vh, 'nbdof');
e = ones(VhNdof,1);
Nmax = 100;
for k = 1:Nmax
Mat = gf_asm('laplacian', im, Vh, Vh, ones(1,VhNdof));
