#include "slepc.h" PetscErrorCode SlepcCheckOrthogonality(Vec *V,PetscInt nv,Vec *W,PetscInt nw,Mat B,PetscScalar *lev)Collective on Vec
V | - a set of vectors | |
nv | - number of V vectors | |
W | - an alternative set of vectors (optional) | |
nw | - number of W vectors | |
B | - matrix defining the inner product (optional) |
If matrix B is provided then the check uses the B-inner product, W'*B*V.
If lev is not PETSC_NULL, it will contain the level of orthogonality computed as ||W'*V - I|| in the Frobenius norm. Otherwise, the matrix W'*V is printed.
