set path of the external matlab function

Hello all,
I am trying to run a Matlab script of my model which in turn uses an external Matlab function. When I run the model from matlab, comsol opens a new Matlab process and tries to call the function. the problem is I am not able to explicitly specify the path of the function being called.
I did add the function's path to Matlab path, but it somehow does not get updated in the new process that comsol opens internally.
Going through Java API documentation, I found that it is possible to set the path of the function using
model.func.create('extm1', 'MATLAB');
model.func('extm1').set('funcs',{<functionname>,<argslist>});
model.func('extm1').set('manpath',<path>)
This however, does not seem to work from Matlab. Any ideas, suggestions?
Also, when I copied the function in Matlab's default path (/home/user/Documents/MATLAB), the script works just fine, it only doesnt work when the path is not default

Dear Jyani,
To set up the function directory path in MATLAB you have three options:
- save the model (in the MPH format) in the same directory as the for the M-functions. In case you set up the model in a M-file, you can still save the model object before running the study. To proceed add the command:
model.save(fullfilename);
- Set the system environment variable COMSOL_MATLAB_PATH with the M-functions directory path.
- Use the Set Path window available in the MATLAB desktop (MATLAB Home ribbon > Environment group). Adding the MATLAB path (with ADDPATH) does not as you the external MATLAB function is evaluate in a separate MATLAB process.
The JAVA API reference guide refers to an obsolete properties, sorry for the confusion.
Best regards,
Rémi Magnard
