//! Stencil calculations

//! One-dimensional case
//! --------------------
//!
//! Example to calculate the central-difference of `sin(x)` function
//! using [N1D1](struct.N1D1.html) stencil and [Torus](torus/struct.Torus.html)
//!
//! ```
//! # extern crate ndarray;
//! # extern crate stencil;
//! # use stencil::*;
//! # use ndarray::*;
//! # fn main() {
//! # let n = 128;
//! let mut a = torus::Torus::<f64, Ix1>::zeros(n);
//! let mut b = a.clone();
//! a.coordinate_fill(|x| x.sin());
//! let dx = a.dx();
//! a.stencil_map(&mut b, |n: N1D1<f64>| (n.r - n.l) / (2.0 * dx));
//! # }
//! ```
//!
//! Two-dimensional case
//! --------------------
//!
//! Example to calculate the central-difference of `sin(x)cos(y)` function
//! using [N1D2](struct.N1D2.html) stencil and [Torus](torus/struct.Torus.html)
//!
//! ```
