Not enough input arguments - can't figure out what f-n missing argument

Hi, I'm trying to test and play with this code:
http://www.mathworks.com/matlabcentral/fileexchange/31112-deflection-of-a-cantilever-beam/content/beam%20deflection/beam_deflection.m
But when I run it, I get "Not enough input arguments" error.
I can't figure out what parameters should I specify beforehand to be able to run the code.
Thanks

How are you running it? Which keys are you pressing, or which menu entries, or what command?

If you attempt to run a function by pressing the Run button, then the function will be started without any input arguments. When the function attempts to access any of the arguments, MATLAB will generate the error about "not enough input arguments". MATLAB will not prompt for the arguments to be given. Also, MATLAB will not use variables of the same name that were created at the command line.
You need to start the function from the command line, passing in the appropriate values. For example, at the command line type
beam_deflection(10 * ones(1,1001), 4.19, 10, 0.01)
