# subtri

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

## Contents

## Syntax

|[F,V]=coneTriMesh(coneRadius,coneHeight,pointSpacing,nTopMin);

## Description

The `coneTriMesh` function creates a triangulated mesh for a cone with a base radius coneRadius and a height coneHeight. The desired node spacing is set by pointSpacing. The parameter nTopMin sets the number of repeated "pie-segments" used to build the cone, and hence also sets the minimum number of points the tip node is connected to.

## Examples

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

coneRadius=2; coneHeight=4; pointSpacing=0.25; nTopMin=6; closeBaseOpt=1; [F,V,C]=coneTriMesh(coneRadius,coneHeight,pointSpacing,nTopMin,closeBaseOpt);

actualMeanPointSpacing = mean(patchEdgeLengths(F,V))

actualMeanPointSpacing = 0.2491
