Can Someone help me to program an arduino uno?

I have an arduino uno and i wired a 3x3 led matrix to it. I really have no idea how to make any code for it to light up in any pattern or anything. I have the cathodes connected to pins 3,5,6. and the anodes connected to pins 9,10,11. Can anyone help show me a link or something that explains how to program it, or give me a sample code to use? thanks

There is an excellent example at:

written by Andrew Tuline.

Don't forget to use the resistors.

i found this link in my original search but when i upload it to my arduino, the whole matrix lights up and stays lit, no pattern or change, any suggestions?
Do you have your setup wired the same as the schematics?

I believe I do. I'm still pretty new to this. I have all the cathodes in each row connected to their own pin and all the abodes in a row connected to their own pin.
