How to handle multiple inputs while writing a matlab function

Question

How to handle multiple inputs while writing a matlab function ? For example if n is the number of parameters to be passed in the run time then how do my function prototype will look ? Any help will be good. Thanks.

Answer 1

An example of function with various number of parameters is:

function my_function(varargin)

% This is an example
min_arg = 1;
max_arg = 6;

% Check numbers of arguments
error(nargchk(min_arg,max_arg,nargin))

% Check number of arguments and provide missing values
if nargin==1
    w = 80;
end

% Your code ...

end

The same is for the output.
