Group Scattered Data Using a Tolerance

This example shows how to group scattered data points based on their proximity to points

of interest.

Create a set of random 2-D points. Then create and plot a grid of equally spaced points on

top of the random data.

x = rand(10000,2);

[a,b] = meshgrid(0:0.1:1);

gridPoints = [a(:), b(:)];

plot(x(:,1), x(:,2), '.')

hold on

plot(gridPoints(:,1), gridPoints(:,2), 'xr', 'Markersize', 6)
