#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.
