How to define a function that can have multiple variables.

For example f(x,y,z) or f(x,y), z is optional. If I list three variables then system uses f(x,y,z), if only 2 variables uses f(x,y).

I know how to use it by nargin function, is there better way to do so?

Thanks.

When you say you know how to do it by nargin, does that mean you are also familiar with varargin? That sounds like what you want.

>> doc varargin

There is an example on this page:

Hi, thanks. Yes, I know how to do it by nargin, by writing a if nargin<3 command.

Could you write an example by using varragin?

Thank you!
