BVSetSizes#

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

Notes#

n and N cannot be both PETSC_DECIDE. If one process calls this with N equal to PETSC_DECIDE then all processes must, otherwise the program will hang.
