VecDuplicateVecsF90#
Creates several vectors of the same type as an existing vector and makes them accessible via a Fortran pointer.
Synopsis#
VecDuplicateVecsF90(Vec x,PetscInt n,{Vec, pointer :: y(:)},integer ierr)
Collective
Input Parameters#
- x - a vector to mimic 
- n - the number of vectors to obtain 
Output Parameters#
- y - Fortran pointer to the array of vectors 
- ierr - error code 
Example of Usage#
#include <petsc/finclude/petscvec.h>
    use petscvec
    Vec x
    Vec, pointer :: y(:)
    ....
    call VecDuplicateVecsF90(x,2,y,ierr)
    call VecSet(y(2),alpha,ierr)
    call VecSet(y(2),alpha,ierr)
    ....
    call VecDestroyVecsF90(2,y,ierr)
Note#
Use VecDestroyVecsF90() to free the space.
