PEPJDGetFix#

Returns the threshold for changing the target in the correction equation.

Synopsis#

#include "slepcpep.h" 
PetscErrorCode PEPJDGetFix(PEP pep,PetscReal *fix)

Not Collective

Input Parameter#

  • pep - the polynomial eigensolver context

Output Parameter#

  • fix - threshold for changing the target

Note#

The target in the correction equation is fixed at the first iterations. When the norm of the residual vector is lower than the fix value, the target is set to the corresponding eigenvalue.
