For example i drawn this curve and i need to increase the distance between this dot ? is it possible. Because in this curve dot are vey close to each other so i would like to increase distance between this dot equally. Can you please modify this curve

th = linspace( pi/2, -pi/2, 100);
R = 0.1;  %or whatever radius you want
x = R*cos(th) + 0.1;
y = R*sin(th) + -0.01;
plot(x,y,'mo','MarkerSize',3); axis equal;

@Rik: Thanks, I share your opinion. The expression "inpolite" allows the user for answering "oh sorry, this was not my intention" and to change the behavior for following posts. Letting others keep the face can support an adjustment of their social interactions.

The trivial solution would be to reduce the numer of points:

% th = linspace(pi/2, -pi/2, 100);  ==>
th = linspace(pi/2, -pi/2, 20);

If this does not solve your problem, explain, what exacty are your inputs and how you define "distance" here. Maybe you want to interpolate a trajectory and determine some intermediate points?
