Hi everyone: #include "petsc.h" PetscErrorCode PetscViewerASCIIOpen(MPI_Comm comm,const char name[],PetscViewer *lab)
#include "petsc.h" PetscErrorCode PetscViewerBinaryOpen(MPI_Comm comm,const char name[],PetscFileMode type,PetscViewer *binv) if the difference between them is that one for ASCII output and the other for Binary output, why are there different parameters? The speed to output matrix is very fast when I use PetscViewerBinaryOpen. However, when I use PetscViewerASCIIOpen, I can't get the matrix output. the code always is running and it has taken about one day! what's the problem? thank you.
