DSGetArrayReal
Returns a real pointer to the internal array of T or D. You MUST call DSRestoreArrayReal() when you no longer need to access the array.
Synopsis
#include "slepcds.h"
PetscErrorCode DSGetArrayReal(DS ds,DSMatType m,PetscReal *a[])
Not Collective
Input Parameters
| ds | - the direct solver context
|
| m | - the requested matrix
|
Output Parameter
| a | - pointer to the values
|
Note
This function can be used only for DS_MAT_T and DS_MAT_D. These matrices always
store real values, even in complex scalars, that is why the returned pointer is
PetscReal.
