Where can I find information about the four letter codes used by the compression parameter of AVIFILE in MATLAB?

I would like to create an AVI-file using a custom codec. The documentation states that I need specify a "four-character code that identifies the codec (typically included in the codec documentation)." I can not locate this four digit code in the codec documentation.

The four-character codes which need to be specified to select the codec are sometimes referred to as FourCC codes. Each codec has a unique four-letter code on Microsoft Windows. There are several websites that list these codes.
For example, to specify the Indeo 5 codec you would use the command
f=avifile('tmpmpg.avi','compression','IV50')
Note that to use a custom codec, it must be installed in your computer.
