DSPEPGetCoefficients#

Returns the polynomial basis coefficients for a DSPEP.

Synopsis#

#include "slepcds.h" 
PetscErrorCode DSPEPGetCoefficients(DS ds,PetscReal *pbc[]) PeNS

Not Collective

Input Parameter#

  • ds - the direct solver context

Output Parameter#

  • pbc - the polynomial basis coefficients

Note#

The returned array has length \(3(d+1)\), where \(d\) is the degree of the polynomial, and should be freed by the user.

Fortran Notes#

In Fortran the user must provide in argument pbc a sufficiently large array.
