# VecDuplicateVecsF90

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

### Synopsis

    VecDuplicateVecsF90(Vec x,int 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(y,2,ierr)

### Notes

Not yet supported for all F90 compilers
