Hello, here is my code
function handle = DrawLink(z,w,h,handle)
pts = [z-w/2, z+w/2, z+w/2, z-w/2; 0, 0, h, h];
X = pts(1,:);
Y = pts(2,:);
if isempty(handle)
handle = fill(X,Y,'b');
end
end
I am trying to create a handle to the plot without plotting it while I make it. How do I do this? Thanks.

Try this:
fh = figure(1);
set(fh, 'Visible','off')
plot(rand(1,10), rand(1,10), 'p')
Then later, when you want to see it:
set(fh, 'Visible','on')
and it magickally appears!

You can always create an empty handle at the current axes and pass it to your function, for example:
handle = plot([],[],'-');
then in your function, the line with the if will get a TRUE
if isempty(handle)
handle = fill(X,Y,'b'); % note that previous handle (from plot) is repalced to fill
end
