The pid function is part of the Control System Toolbox. It was introduced in R2010b.

You want to use the function 'pid':
but you get an error?
Did you check that you have the control system toolbox, which pid is a part of? You can type 'ver' at the command console and the result will tell you what toolboxes you have.

You will have to buy the toolbox, you can do this on this website (i.e. click on 'products' at the top of the webpage) or by going to your Matlab, click on the 'Apps' tab in the console window and select 'get more apps'.
