#include "petscksp.h" PetscErrorCode KSPSetResidualHistory(KSP ksp,PetscReal a[],PetscInt na,PetscBool reset)Not Collective
| ksp | - iterative context obtained from KSPCreate() | |
| a | - array to hold history | |
| na | - size of a | |
| reset | - PETSC_TRUE indicates the history counter is reset to zero for each new linear solve |
Notes: The array is NOT freed by PETSc so the user needs to keep track of it and destroy once the KSP object is destroyed.
If 'a' is PETSC_NULL then space is allocated for the history. If 'na' PETSC_DECIDE or PETSC_DEFAULT then a default array of length 10000 is allocated.
