   for i = 1:length(counties)
       x(i).min = min(counties(i).Lon);
       x(i).max = max(counties(i).Lon);
       y(i).min = min(counties(i).Lat);
       y(i).max = max(counties(i).Lat);
       vector(i).x = x(i).min:x(i).max;
       vector(i).y = y(i).min:y(i).max;
   end

Here is what I get:

What's wrong with the result as you've shown it? What did you expect instead?

Isn't min(counties(i).Lon) the same as counties(i).Lon??? You are taking the min of only a single value. Or is the Lon field actually an array of several numbers?

What is counties(20).Lon, counties(20).Lat, and same for elements 1 and 24? They appear to be 2 element arrays, unlike the other elements. Why?
