MatISSetAllowRepeated

Set the flag to allow repeated entries in the local to global map

Synopsis

#include "petscmat.h" 
PetscErrorCode MatISSetAllowRepeated(Mat A, PetscBool flg)

Logically Collective

Input Parameters

• A - the matrix

• flg - the boolean flag

Notes

The default value is PETSC_FALSE. When called AFTER calling MatSetLocalToGlobalMapping() it will recreate the local matrices if flg is different from the previously set value. Specifically, when flg is true it will just recreate the local matrices, while if flg is false will assemble the local matrices summing up repeated entries.
