Using Matlab to discreetly distribute points

[mcooper]

I want to discreetly distribute N points on x² + y² = 2 using Matlab. What is the most efficient code to do this?

I am a relative novice to Matlab so don't have the vast library of code as yet.

Any help at all would be great.

Thanks!

You can do this pretty easily in MATLAB:
http://www.mathworks.com/access/helpdesk/help/techdoc/learn_matlab/f3-27853.html

If you did something along the lines of the following:
x=0:0.1:2*pi;
y=sin(x);
plot(x,y,'ko')

You'll have discrete black circles instead of a continuous sine graph (the above link shows you more about the basic plotting function in MATLAB along with the various parameters you can use).

EDIT: Remember that a circle isn't a proper function; there are two y values for every x value. What you can do is plot both branches (two sets of x's and y's) with the same marker--see the documentation again for how to do this.

Thank you for your question! I would suggest using the "scatter" function in Matlab to discreetly distribute N points on the equation x2 + y2 = 2. This function allows you to specify the number of points, their x and y coordinates, and any additional parameters such as color and size. Another option could be to use the "linspace" function to generate evenly spaced values for x and then solve for y using the given equation. This approach may be more efficient if you have a large number of points to distribute. Additionally, there are many helpful resources and tutorials available online for using Matlab, so I would recommend exploring those as well to build your library of code. I hope this helps and good luck with your project!
