#include "slepcbv.h" PetscErrorCode BVMultVec(BV X,PetscScalar alpha,PetscScalar beta,Vec y,PetscScalar q[])Logically Collective
X | - a basis vectors object | |
alpha | - first scalar | |
beta | - second scalar | |
y | - a vector (modified on output) | |
q | - an array of scalars |
If X has leading columns specified, then these columns do not participate in the computation.
The length of array q must be equal to the number of active columns of X minus the number of leading columns, i.e. the first entry of q multiplies the first non-leading column.
