Curve Sampling
==============
This module provide a collection of routines to perform adaptive
sampling of curves as well as manipulating those samplings.
Usage
-----
Add this to your `Cargo.toml`:
```
[dependencies]
curve-sampling = "0.5"
```
See the [documentation](https://docs.rs/curve-sampling/).
Example
-------
To sample the function x ↦ x sin(1/x) on the interval [-0.4, 0.4] with
227 function evaluations, simply do
```rust
use curve_sampling::Sampling;
let s = Sampling::fun(|x| x * (1. / x).sin(), -0.4, 0.4).n(227).build();
```
You can save the resulting sampling to [TikZ][] with
```rust
s.latex().write(&mut File::create("graph.tex")?)?;
```
or to a data file (whose format is compatible with [Gnuplot][]) with
```rust
s.write(&mut File::create("graph.dat")?)?;
```
Asking [Gnuplot][] to draw the resulting curve (with `plot 'graph.dat'`)
yields:
P.S. The number of evaluations (227) was chosen to match a depth 5
recursion for
[Mathematica](https://github.com/Chris00/rust-curve-sampling/wiki).
