Redirecting Command Window output to stdout using mlcaller, error

I am trying to redirect the Command Window output to stdout and stderr when running MATLAB in batch mode. I found this link that answers my question: http://www.mathworks.com/support/solutions/en/data/1-ACT3YN/index.html?product=ML&solution=1-ACT3YN

However, after following the steps, I receive an error: ??? Undefined function or variable 'myFunction'. I don't understand why I am receiving this error, because the function is defined.

Here is my code:

@echo off
echo "running..."
mlcaller "cd 'C:\Documents and Settings\My Documents\folder';myFunction('file.dat','data.txt');"
echo "complete"

mcaller will, if I understand correctly, be a .exe that you would invoke, and you would not invoke MATLAB yourself. mcaller will start up MATLAB and run the named command "myFunction" (which is what your .m file would have to be named.)

Oh! I did not know that mlcaller also ran the function, as well as print to standard out. Thanks!

I still don't know why it says it's undefined. "myFunction" is the name of my function.

Is myFunction.m in your current directory?

Experiment with

mcaller "which -all myFunction"

Note: when you finally do get it finding myFunction, you will need to pass the arguments in the mcaller invocation, such as

mcaller "myFunction('file.dat','data.txt')"

When I try mcaller "which -all myFunction" the error goes away, but now standard output says "'myFunction' not found." I am sure that it is in the correct directory.

I now have tried this:

mlcaller "cd 'C:\Documents and Settings\My Documents\folder';myFunction('file.dat','data.txt');"

I do not receive any errors any more, and it runs, but it does not output anything to standard out.
