Newbie question about example on a textbook

Hi guys, i just started learning using MATLAB. I am following the "MATLAB for neuroscientist" textbook's examples. I came across this code that won't work:

if true
  % code
end
figure
for ii = 1:9
  subplot(3,3,ii)
  h = bar(1,1)
  set(h,'FaceColor',[0 0 ii/9])
end

This code i copied it from the text book in this exact way but when i try to run it it says: Attempt to execute SCRIPT subplot as a function: D:\Program Files\MATLAB\R2013a\bin\subplot.m

Error in subplot (line 3) subplot(3,3,ii)

obviously i can't understand where the problem is, thank you in advance!

You probably saved your file as subplot.m

It conflicts with the subplot() function and built-in subplot.m

Name it something else.

magic! whoa thank you, that was exactly the problem!
