# patchEdges

Below is a demonstration of the features of the `patchEdges` function

## Contents

```
clear; close all; clc;
```

## Syntax

| [E] = patchEdges(F,uniOpt);|

## Description

Get the nx2 patch array for the input faces (F) and vertices (V). If uniOpt=1 then only unique edges are returned e.g. the edges spanning from node 1 to node 2 is the same as from node 2 to node 1. If uniOpt=0 then such non-unique edges are also inluded.

## Examples

Example geometry

[F,V]=geoSphere(1,1); uniOpt=0; E=patchEdges(F,uniOpt); cFigure; subplot(1,2,1); title('Patch geometry') gpatch(F,V,'rw','r'); axisGeom; camlight headlight; subplot(1,2,2); title('Edges') gedge(E,V,'r',2); axisGeom; drawnow;
