converts nan separated succeeding vertex lists into a vertex list and an edge list

Description

This function removes the NaN from the original point list. The orientation (cw/ccw) is not changed. It is exactly the same as PLELofCPL

Example Illustration

Syntax

[VL,EL]=VLELofCVL(CVL)

Input Parameter

CVL: NAN Separated Vertex List

Output Parameter

`VL`:		Vertex List (without NaN)
`EL`:		Edge list

Examples


[VL,EL]=VLELofCVL(VLsample(19)); CVL=CVLofVLEL(VL,EL); VLELofCVL(VLsample(19));

Algorithm (Workflow)

This function, VLELofCVL, is designed to convert a NaN-separated vertex list (CVL) into a vertex list (VL) and an edge list (EL). It is part of the SolidGeometry library and was introduced in version 4.1.

Input Parameters

CVL: A NaN-separated vertex list. This list contains vertices separated by NaN values, which indicate breaks between different sets of vertices.

Output Results

VL: A vertex list without NaN values. This list contains all the vertices from the input CVL, but with the NaN values removed.
EL: An edge list. This list defines the edges between the vertices in the VL.

Algorithm Steps

The function calls PLELofCPL with the input CVL. This function is responsible for removing NaN values and generating the vertex and edge lists.
If no output arguments are specified (i.e., nargout==0), the function will create a 3D plot of the vertices and edges using the SGfigure and VLELplots functions.
The view for the plot is set to an angle of -30 degrees in azimuth and 30 degrees in elevation.
The size of the plot markers is determined by the bounding box size, calculated using sofBB(BBofVL(VL)), and scaled by a factor of 1/20.

Example Usage

An example of how to use this function is provided in the comments:

[VL,EL]=VLELofCVL(VLsample(19)); 
CVL=CVLofVLEL(VL,EL); 
VLELofCVL(VLsample(19));

This example demonstrates converting a sample vertex list into a CVL and back into a VL and EL.
