Returns a pointer to the internal array of one of the matrices. You MUST call DSRestoreArray() when you no longer need to access the array.

#include "slepcds.h" 
PetscErrorCode DSGetArray(DS ds,DSMatType m,PetscScalar *a[])

Not Collective

Input Parameters#

  • ds - the direct solver context

  • m - the requested matrix

Output Parameter#

  • a - pointer to the values

Note#

To get read-only access, use DSGetMat() followed by MatDenseGetArrayRead().
