Answer 1

[Walter Roberson]

xy0 = randi(100, 1, 2)   %cm, 10 m

xy0 = 1×2

40 43

radius = 10;  %cm, 1 m
rand_angle = rand(1,1) * 2*pi;
[dx, dy] = pol2cart(rand_angle, radius);
xy1 = xy0 + [dx, dy]

xy1 = 1×2

48.7295 47.8781

plot(xy0(1), xy0(2), 'k.', xy1(1), xy1(2), 'b*');
xlim([0 100]); ylim([0 100]);
legend({'original point', 'point 1 m away'});
xlabel('cm'); ylabel('cm')
