How to give inputs to function definitions?

I know this is a dumb question but I have to ask, else i'l never know how to do it. I am stuck without any knowledge as how to give input to functions. for example, In this link http://www.mathworks.in/matlabcentral/fileexchange/20328 the file is defined in a function and when i execute it, it shows 'Not enough input arguments.'. Now this is my problem. How should I give inputs to this function and also how to define them in a separate file. Pls help and thanks in advance.

In Matlab windows command type

costMat=magic(5)
[assignment,cost] = munkres(costMat)

Thanks you very much, can i define this input in a separate file?

You can call the function in windows command or in an m-file, your function and your m-file should be in the same folder
