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:

![x sin(1/x)](https://user-images.githubusercontent.com/1255665/186882845-81dcbe02-808b-40d7-9fad-a838e326ce78.png)

P.S. The number of evaluations (227) was chosen to match a depth 5

recursion for
