/// Fungsi ini menghitung solusi terhadap Persamaan Poisson

///  \f[
///   \nabla^{2}(r,\phi,z) = \rho(r,\phi,z)
///  \f]
///
/// dengan diketahui nilai tepi (Boundary Value) pada \f$V\f$ (potensial) dan distribusi buatan \f$\rho\f$
///
/// \param[in,out] VPotential float[nrows*ncols*nphi] distribusi potensial. Input: hanya nilai tepi. Output: hasil perhitungan penyelesaian persamaan Poisson
/// \param[in]  RhoChangeDensity float[nrows*ncols*nphi] distributsi muatan listrik. 
///
/// \return A fixed number that has nothing to do with what the function does
