Various functions to process spectra. Those are `pure` functions.

They are sorted in various categories:

- matrix: functions on ml-matrix instances (or array of arrays)
- x: functions that apply on a 1D array
- xy: functions that apply on an object `{x: [], y:[]}`
- xy2: functions that apply on an array of arrays of 2 numbers `[[x,y], [x,y]]`
- xyArray: functions that apply on an array of objects `{x: [], y:[]}`
- xyObject: functions that apply on an array of point `[{x,y}]`
- xreim: functions that apply on an object `{x: [], re:[], im:[]}`
- reim: functions that apply on an object `{re: [], im:[]}`
- reimArray: functions that apply on an array of objects `{re: [], im:[]}`
- reimMatrix: functions that apply on an object of matrices `{re, im}`
- zones: functions that apply on an array of zone `[{from,to}]`

The name of the functions start with the first argument on which they apply.

## Installation

```console
npm install ml-spectra-processing
```

## Usage

```js
import { xAdd } from 'ml-spectra-processing';

const array = [1, 2, 3];
const result = xAdd(array, 5);
console.log(result);
```
