When I attempt to pcode any function, however basic the same error message appears 'Not enough input arguments' this error occurs the first time any input argument to the function is used. If I attempt to write a function without any arguments and pcode it, it returns the error 'Input argument must be a nonempty string.'

Again, I must emphasise that the functions themselves work, and return no error messages. The only time error messages appear is when I attempt to pcode them.

I have just updated from 2006b (yes I know very old!) so I need to redo all of my previous pcodes in this version but cannot! Any help would be MUCH appreciated.

PCODE requires the NAME of the function from which the p-coded file is to be generated as input. In your first attempt you're calling main2048 with the variable dataset as input and attempting to use whatever it returns as the name of the file to pass into PCODE. In your second attempt you're calling main2048 with no input arguments and attempting to use whatever that returns as the name of the file.

Try:

pcode('main2048')

Ignore above. I wasn't using the correct call. It should be:

pcode main2048

This worked fine.

It might be you have something other called pcode on your path. Please execute

which pcode -all

It should return only something like this

C:\Program Files\MATLAB\R2014a\toolbox\matlab\general\pcode.m

If you have more, you know which function or variable casues the trouble.

Thank you, but unfortunately I have tried this and there is only one pcode on the path!

I know this is probably obvious, but you are using "pcode" correctly?

pcode filename

pcode('filename')

Thank you- the obvious ones are sometimes the answers! My syntax was correct however I have tried changing my function names to all lower case and this seems to work. It may just have been my computer!

I get the same error when using pcode. If I rename my file to all lower case it still gives the same error?? I'm using 2014b

Please provide the information asked by Philip and I:

"Post the exact commands you are typing and errors you get and example of a function you are attempting to pcode and even the .p file you have produced by pcoding it."

and

which pcode -all
