Computes Y = Y + alpha*X.

Synopsis

#include "slepcbv.h" 
PetscErrorCode BVAXPY(BV Y,PetscScalar alpha,BV X)
Logically Collective on BV

Input Parameters

Y,X - basis vectors
alpha - scalar

Output Parameter

Y - the modified basis vectors

X and Y must be different objects, with compatible dimensions. The effect is the same as doing a VecAXPY for each of the active columns (excluding the leading ones).
