Hi,

I have the source coordinates (x,y) and destination coordinates (DX,DY). I want to animate a point move from source to destination. There is no graph used. Can anyone please help.

I am not sure what you mean when you say "there is no graph used", but maybe something like the exa,ple below might help.

clear,clc
x0 = [20 150];                  % x coordinates of source and destination
y0 = [30 100];                  % y coordinates of source and destination
slope = diff(y0)/diff(x0);
x = linspace(20,150,500);
y = slope*(x-x0(1))+y0(1);
figure(1)
for i = 1:length(x)
    plot(x(i),y(i),'ok','MarkerFaceColor','r')
    axis([10 160 20 110])
    drawnow
end

Thank you. I have only 2 points coordinates (20,30) which is to be moved to (150,100). These coordinates are predefined. Can you help a bit more with this?

HI @Aasha M V, I have edited the code above according to your specific case. Note that it'd be difficult to clearly see the animation, since it's only 2 points and it happens quite fast. Therefore, I made the point move more smoothly by defining more points lying on the straight line between your source and your destination.
