VecDuplicateVecsF90

Creates several vectors of the same type as an existing vector and makes them accessible via a Fortran90 pointer.

Synopsis

VecDuplicateVecsF90(Vec x,PetscInt n,{Vec, pointer :: y(:)},integer ierr)
Collective on Vec

Input Parameters

x - a vector to mimic
n - the number of vectors to obtain

Output Parameters

y - Fortran90 pointer to the array of vectors
ierr - error code

Example of Usage

    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)
