How to write functions with input propertys?

MATLAB has a lot of functions with input propertys. As an example:
plot(...,'PropertyName',PropertyValue,...)
When my own functions are getting lots of input arguments its often looking like this:
myfcn(X,Y,[],[],[],[],[],[],[],[],[],[],[],b)
For this situations I want to learn how to write functions with input propertys.
Is it explained somewhere in the matlab help? Is that object oriented programming? Is there a function that I can open and learn from? (I found only 'Built-in functions') Which keywords can I use for google etc.

Thank you all. Parse was the missing node. I'd like to accept all answers, so let me take the first.

This is a good point to start from: http://blogs.mathworks.com/community/2012/02/13/parsing-inputs/ . You can find further links by searching for "Matlab parse inputs". The method to use a name of a property and the its value is called "property value pair".
Object oriented programming is another topic.

Here are some links to the File Exchange. The first, parse_pv_pairs, is especially well documented.
And search "Parse Function Inputs" and "inputParser" in the on-line help.
