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!

I do not understand what you want to do, or what your requirements are.

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
