I made a patch on plot.
i wanted to make a same patch on a geoplot. but it didn't work.
It would be good if you explain with 4 coordinates. do not mind 'z' value I will make a patch on 2d geoplot.
The coordinates is
x = [126.509 126.508 126.511 126.512]
y = [37.403 37.4063 37.4048 37.4081]
Thanks.

You data is not in correct order. The axis scale is also not proportional. Try geoplot if you have mapping toolbox.
x = [126.509 126.508 126.511 126.512];
y = [37.403 37.4048 37.4081 37.4063]; % The original data order is incorrect
% geoplot
figure
geoplot(y([1:end 1]), x([1:end 1]))
geobasemap streets
% normal plot
figure
plot(x([1:end 1]), y([1:end 1]))
axis equal

Just "hold on" and plot all rectangles.

x = [126.509 126.508 126.511 126.512] ;
y = [37.403 37.4063 37.4048 37.4081] ;
patch(x,y,'r')
In case, you looking for:
[val,idx] = sort(x) ;
patch(x(idx),y(idx),'r')

Patch does not work well on geoplot. Thanks
