#include "slepcip.h" PetscErrorCode IPQRDecomposition(IP ip,Vec *V,PetscInt m,PetscInt n,PetscScalar *R,PetscInt ldr,Vec work)Collective on IP
ip | - the eigenproblem solver context | |
V | - set of vectors | |
m | - starting column | |
n | - ending column | |
ldr | - leading dimension of R | |
work | - workspace vector |
In some cases, this routine makes V B-orthonormal, that is, V'*B*V=I.
If one of the vectors is linearly dependent wrt the rest (at working precision) then it is replaced by a random vector.
