fnct to detect crossing segments of a circ line with a CPL
Description
Function to detect crossing angles for crank and follower attchment point path in fourbar linkage design tasks. Resolution is one degree;
Could be speed up by ray beam analysis instead of CPL subtraction

Syntax
[wlim,winv]=CPLcrosscircseg([CPLA,A0,wlim])
Input Parameter
CPLA: | | CPL of restricted Area |
A0: | | Center of circular movement |
wlim: | | angle interval of circular movement; default is [0 2*pi] |
Output Parameter
wlim: | | list of crossed angle segments (right hand) |
winv: | | inverse angle segments of wlim (right hand) |
Examples
CPLcrosscircseg(CPLsample(3),[0 10 4 0.1]) % A0=[0 10] r=4; d=0.1
CPLcrosscircseg(CPLsample(3),[0 10 4 0.1],[1.2*pi,2.4*pi]) % A0=[0 10] r=4; d=0.1
CPLcrosscircseg(CPLsample(3),[0 -6 4 0.1],[1.2*pi,2.4*pi]) % A0=[0 10] r=4; d=0.1
CPLcrosscircseg(CPLsample(3),[6 0 4 0.1],[1.2*pi,2.4*pi]) % A0=[0 10] r=4; d=0.1
CPLcrosscircseg(CPLsample(3),[5 -6 4 0.1],[1.2*pi,2.9*pi]+pi/6)
