KSPFCGSetMmax#
set the maximum number of previous directions FCG will store for orthogonalization
Synopsis#
#include "petscksp.h"
PetscErrorCode KSPFCGSetMmax(KSP ksp, PetscInt mmax)
Note: mmax + 1 directions are stored (mmax previous ones along with a current one) and whether all are used in each iteration also depends on the truncation strategy (see KSPFCGSetTruncationType())
Logically Collective on ksp
Input Parameters#
