Syntax

[NPL,FFL]=CPLofPLcrossCPL(CPL,PL,[LL])

Input Parameter

`CPL`:		Closed Polygon line
`PL`:		Point List
`LL`:		Optional Length or angle list related to the points of PL

Output Parameter

`FFL`:		Interpolated Value List

Examples


CPLofPLcrossCPL(PLcircle(10,8),[-15 -15;+15 -15]) % No crossing
CPLofPLcrossCPL(PLcircle(10,8),[-15 -15;+15 +15]) % Crossing
CPLofPLcrossCPL(CPLsample(13),[-15 -15;+15 +15])  % three crossings
CPLofPLcrossCPL(PLcircle([10,4,3],8),[-20 20;-5 -5; -4 -4; 5 5; 20 20]) % Crossing
