# mesh-laplacian

Computes the Laplacian of a mesh.

## Install

```

npm i mesh-laplacian

```

## Example

```javascript

var bunny   = require('bunny')

var lapList = require('mesh-laplacian')(bunny.cells, bunny.positions)

var lapMat  = require('csr-matrix').fromList(lapList)

```

## API

#### `var mat = require('mesh-laplacian')(cells, positions)`

Constructs the mesh Laplacian for a given surface mesh using barycentric cotangent weights.

* `cells` are the faces of the mesh

* `positions` are the coordinates of the vertices of the mesh

**Returns** A list of entries of the form `[vi,vj,w]` representing the entries

of the Laplaican matrix for the mesh.
