[petsc-users] How to view petsc array?

I need to check the contents of the array which was declared using:

PetscScalar,pointer :: 

I tried to use :

call PetscViewerASCIIOpen(MPI_COMM_WORLD,"pres.txt",viewer,ierr)

call VecView(p_array,viewer,ierr)


call MatView(p_array,viewer,ierr)

call PetscViewerDestroy(viewer,ierr)

but I got segmentation error. So is there a PETSc routine I can use?

Thank you

Yours sincerely,
