Hi,
I created the identity matrix by the following lines: Provided M is the
mass matrix
I = M;
I.zero();
I.ident_zeros();
I.compressed(I);
After the upgrade to dolfin-1.5.0 the last line gives the following error:
***

*** Error: Unable to init PETSc matrix.
*** Reason: PETScMatrix may not be initialized more than once..
*** Where: This error was encountered inside PETScMatrix.cpp.
*** Process: unknown
***
*** DOLFIN version: 1.5.0

Is it a bug or there is a different way of using matrix.compressed?
Thank you for your comment.
Regards,
Murtazo
