How can I use subplots with an inside function?

I am trying to create a figure with 6 subplots. My 'polygon' function creates a regular plot. The subplot command doesn't seem to recognize the function as a plot, and only the last plot is displayed (as a full plot). What am I missing? Thanks!
function draw_polygons()
subplot(2,3,1)
polygon(3);
subplot(2,3,2)
polygon(4);
subplot(2,3,3)
polygon(5);
subplot(2,3,4)
polygon(6);
subplot(2,3,5)
polygon(7);
subplot(2,3,6)
polygon(8);
end

What happens if you just do
subplot(2,3,1)
subplot(2,3,2)
subplot(2,3,3)
subplot(2,3,4)
subplot(2,3,5)
subplot(2,3,6)

Are you saying that this code does not produce 6 plots? Because it does for me (both functions are in test.m):
function test
subplot(2,3,1)
polygon(3);
subplot(2,3,2)
polygon(4);
subplot(2,3,3)
polygon(5);
subplot(2,3,4)
polygon(6);
subplot(2,3,5)
polygon(7);
subplot(2,3,6)
polygon(8);
end
function polygon(sides)
degrees=2*pi/sides;
theta=0:degrees:2*pi;
radius=ones(1,numel(theta));
graph=polar(theta,radius);
set(graph,'color','b','linewidth',2)
end

It should work in a single file, or two different m-files. You must have a close() or clf in there somewhere.

make sure you don't have a close or figure command inside of polygon
you could always try to step through with debugger to find out exactly what is happening in your code

Yeah I had a clf command inside polygon. Works perfectly now. Thanks!

I guess your problem is that you always open a new figure in your polygon function. So take out figure() and it should work.
