creating a polygon using device
3 Ansichten (letzte 30 Tage)

I have 2 functions in matlab t.go (which moves my device 0.1 units forward starting at the origin, facing absolute right at the star) and t.turn(angle) which turns the device with an angle you input. How would I go about drawing I would say a 25 sided polygon around the origin who's distance from the origin to the edge of the polygon is 5.

Do you mean like this:
theta = 0 : 360/25 : 360;
x = 5 * sind(theta);
y = 5 * cosd(theta);
plot(x, y, 'b*-', 'LineWidth', 2);
grid on;
hold on;
axis square
% Draw lines from origin to the points in red
for k = 1 : length(y)
plot([0,x(k)], [0, y(k)], 'r-');
end

If you want the angle to turn from one side to head towards the next (x, y) location, that's just simple high school trigonometry that I would think you can handle. Let me know if you can't figure it out.
