Synopsis
#include "slepcds.h"
PetscErrorCode DSSetCompact(DS ds,PetscBool comp)
Logically Collective
Input Parameters
| ds | - the direct solver context
|
| comp | - a boolean flag

Notes
Compact storage is used in some DS types such as DSHEP when the matrix
is tridiagonal. This flag can be used to indicate whether the user
provides the matrix entries via the compact form (the tridiagonal DS_MAT_T)
or the non-compact one (DS_MAT_A).
The default is PETSC_FALSE.
