Intersection sensor Polygon and the road points (curves)

hello,

I wrote this code with the help of my friends to get Intersections of polygons and curves.

i now want the total time and the time increase with call the function and how can i call the function in matlab.

for the intersection i used the InterX function ,can you tell me please how can i use the Polyxpoly funktion in this case ,i found in my execusion no intersections also when i want only drawing the sensor polygon i got no result

my code:

roadRadiusM = 300;

roadOriginM = [0,roadRadiusM,0];

roadSegmentM = [-60,-10];

roadRadiusN = 280;

roadOriginN = [0, roadRadiusM, 0];

roadSegmentN = [-60,-10];

tM = linspace(roadSegmentM(1),roadSegmentM(2),8);

xlimitM = roadRadiusM*cosd(tM)+roadOriginM(1);

ylimitM roadRadiusM*sind(tM)+roadOriginM(2);

plot(xlimitM, ylimitM, 'r')

tN = linspace(roadSegmentN(1),roadSegmentN(2),8);

xlimitN = roadRadiusN*cosd(tN)+roadOriginN(1);

ylimitN = roadRadiusN*sind(tN)+roadOriginN(2);

plot(xlimitN, ylimitN, 'r')

xlimit = [xlimitM, NaN, xlimitN];

ylimit = [ylimitM, NaN, ylimitN];

% two sensor

fovLengthA = 300;

fovOriginA = [-40,30,0];

fovAngleA = 12;

fovLengthB = 200;

fovOriginB = [-10,50,0];

fovAngleB = 35;

[xFoVA, yFoVA] = CircleArc(-1/2*fovAngleA, 1/2*fovAngleA, fovOriginA, fovLengthA);

[xFoVB, yFoVB] = CircleArc(-1/2*fovAngleB, 1/2*fovAngleB, fovOriginB, fovLengthB);

patch('XData', xFoVA, 'YData', yFoVA,...

'FaceColor', 'none', 'EdgeColor', 'r',...

'LineStyle', '-');

patch('XData', xFoVB, 'YData', yFoVB,...

'FaceColor', 'none', 'EdgeColor', 'g',...

'LineStyle', '-');

A = InterX([xlimit; ylimit], [xFoVA; yFoVA]);

plot(A(1,:),A(2,:),'ko')

B = InterX([xlimit; ylimit], [xFoVB; yFoVB]);

plot(B(1,:),B(2,:),'kx')
