analyzes the crossings of two vertex lists

Description

returns a X=[a b c d e] vector that has the following elements
a: number of PL vertices which are on the contour VL
b: number of PL vertices which are outside of the contour VL
c: number of PL vertices which are inside of the contour VL
d: crossings of the edges of contour PL with contour VL
e: only real crossings

Syntax

[X,CCL,EPL]=inside2C(VL,PL,[debug])

Input Parameter

VL: Vertex list of the contour
PL: 2nd contour to be analyzed
debug: shows text if debug is true, default is false

Output Parameter

X: Result vector
CCL: Crossing contour lines list
EPL: Result matrix for each point of PL

Examples

How to used inside2C
inside2C(PLcircle(10,8),[-15 -15;15 15])
n=size (PL,1); X=inside2C (VL,PL);
if X(3)==n; disp 'fully inside'; end;
if X(2)==n; disp 'fully outside'; end;
CPLofPLcrossCPL(PLcircle(10,8),[-15 -15;15 15])
