I tried it both in windows and unix, and I just dont understand why it happens. I have a function in its file.
% Beginning of file
function [MarginPOR] = creditFunc_prod1 ( Notional , MaxNotional )
%Linearly interpolate the probability of loss and stressed loss greater than 0
display('Using the OFFICIAL UNIX PRODUCTION creditFunc...');
MarginPOR = Notional + MaxNotional;
end
% End of file
Then I do this two,
>> pcode(creditFunc_prod1, '-inplace');
Using the OFFICIAL UNIX PRODUCTION creditFunc...
??? Input argument "Notional" is undefined.
Error in ==> creditFunc_prod1 at 7
MarginPOR = Notional + MaxNotional;
>> a= creditFunc_prod1(1,2)
Using the OFFICIAL UNIX PRODUCTION creditFunc...
a =
3
>>
If someone can help me understand why this happens, it will be really great.

ok, i wait wait wait and figured out myself. matlab documentation is wrong. here is what is in this document, http://www.mathworks.com/help/matlab/ref/pcode.html
"...pcode(fun) encrypts the code in fun.m and produces a file called fun.p, known as a P-file. ..."
In fact, this fun has to be a string of directory or full file name,
>> modeldev = '/home/jincao/pcodedir/';
>> pcode(modeldev,'-inplace');
this worked.

The documentation is fine. However, the fun input is supposed to be the file name:
pcode('creditFunc_prod1', '-inplace');
Note the quotes around the first argument. As you were calling it, Matlab interpreted the first argument not as the name of the function but as a call to the function, and tried to run it as presented, with no arguments. That leads to the error.
So it's not pcode that's complaining, but your own function.

to people who knows how to use this function, it is piece of cake. But to people who has never use this function before,
this line is just misleading, "...pcode(fun) encrypts the code in fun.m and produces a file called fun.p, known as a P-file. ..."
anyone reads this line will do this,
pcode(fun);
