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.
