Sets the local and global sizes, and the number of columns.

Synopsis

#include "slepcbv.h" 
PetscErrorCode BVSetSizes(BV bv,PetscInt n,PetscInt N,PetscInt m)

Collective

Input Parameters

• bv - the basis vectors

• n - the local size (or PETSC_DECIDE to have it set)

• N - the global size (or PETSC_DECIDE)

• m - the number of columns

n and N cannot be both PETSC_DECIDE. If one processor calls this with N of PETSC_DECIDE then all processors must, otherwise the program will hang.
