Try this:
ad = 89.8412; % Angle (Degrees)
tangline = 200*[0 cosd(ad); 0 sind(ad)];
figure
plot(tangline(1,:), tangline(2,:))
grid
axis([0 2 0 300])
It produces two vectors in the ‘tangline’ matrix, the first row being the x-coordinates and the second row the y-coordinates. It then plots them.
You can check that these are correct with:
Check = atan2d(diff(tangline(2,:)), diff(tangline(1,:)))
It returns the ‘ad’ value.
