#include "slepcip.h" PetscErrorCode IPOrthogonalize(IP ip,PetscInt nds,Vec *defl,PetscInt n,PetscBool *which,Vec *V,Vec v,PetscScalar *H,PetscReal *norm,PetscBool *lindep)Collective on IP and Vec
| ip | - the inner product (IP) context | |
| nds | - number of columns of defl | |
| defl | - first set of vectors | |
| n | - number of columns of V | |
| which | - logical array indicating columns of V to be used | |
| V | - second set of vectors |
| H | - coefficients computed during orthogonalization with V | |
| norm | - norm of the vector after being orthogonalized | |
| lindep | - flag indicating that refinement did not improve the quality of orthogonalization |
On exit, v = v0 - V*H, where v0 is the original vector v.
This routine does not normalize the resulting vector.
