Hi
Im doing data fitting and am interested in plotting a line from the data to the fitted curve, see wikipedia image.
Thats exactley what i want i just cant seem to plot the residuals like they have done.
This is my code
clear, clc
x = 0:pi/10:2*pi;
y = sin(x);
yx = random('ev',y,0.2);
plot(x,y,x,yx,'o'), axis([0-0.1 2*pi+0.1 min(yx)-0.1 max(yx)+0.1])
thanks

Add to your code:
hold on;
line([x;x], [yx;y],'color','green');
plot(x,yx,'bo','markerfacecolor','blue');
You can tweak the colors as necessary.
