#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 NULL then space is allocated for the history. If 'na' PETSC_DECIDE or PETSC_DEFAULT then a default array of length 10000 is allocated.
