Synopsis

VecRestoreArrayReadF90(Vec x,{Scalar, pointer :: xx_v(:)},integer ierr)

Logically Collective

Input Parameters

• x - vector

• xx_v - the Fortran pointer to the array

Output Parameter

• ierr - error code

Example of Usage

    use petscvec

    PetscScalar, pointer :: xx_v(:)
    ....
    call VecGetArrayReadF90(x,xx_v,ierr)
    a = xx_v(3)
    call VecRestoreArrayReadF90(x,xx_v,ierr)
