array-unflat

============

The opposite of Array.prototype.flat() with depth = 1.

Useful to convert one-dimensional arrays `[x, y, z, x, y, z]` into two-dimensional arrays `[[x, y, z], [x, y, z]]` i.e. for [simplicial complex](https://github.com/mikolalysenko/simplicial-complex).

## Install

```

npm install array-unflat

```

## Example

```js

const unflat = require('array-unflat');

const arr = [0.2, 0.3, 0.5, -1.8, 2.9, 1.1];

console.log(unflat(arr));

console.log(unflat(arr, 3));

```

Output:

```js

[ [0.2, 0.3], [0.5, -1.8], [2.9, 1.1] ]

[ [0.2, 0.3, 0.5], [-1.8, 2.9, 1.1] ]

```

## Usage

#### `unflat(arr, size)`

- `arr` the flattened array

- `size` (default `2`) length of the grouped subarrays

**Returns** a two-dimensional array.
