在 MATLAB Online 中打开

Try this:

deg = 0 : 5 : 90;
r = 1;
x = r*[zeros(size(deg(:))) cosd(deg(:))];
y = r*[zeros(size(deg(:))) sind(deg(:))];
figure
plot(x', y', 'LineWidth',2)
axis equal

Here, ‘r’ (the radius value) defines the end points for each line. If you want different lengths for each line, ‘r’ becomes a (19x1) vector with a different value assigned to each element.
