Hi,
I have just conneted to AWS to get several workers running my code. However the error message below comes up without any clue of what file should I include in the workers. Apparently they need a function 'isShapeOnXY' which I don't know what it is about, and matlab offers me to addAttachedFiles() to upload the file to the worker, buy since I don't know what 'isShapeOnXY' is I don't know what file should I provide. What's more, the error is just using a mere '+' sign, when I go to the function where the problem is, I find that is a very simple operation.
Of course, when I do parallel computing in my local everything works perfectly.
I would appreciate if sb could give some gidance on how to get around this issue.

An UndefinedFunction error was thrown on the workers for 'isShapeOnXY'. This might be because the file containing

The method isShapeOnXY is required by class shape.Shape. Somehow it looks like this is missing from your AWS instance. It should be under <matlabroot>/toolbox/shared/em_cad/authoring for the most recent release of MATLAB. How are you setting things up with AWS? Which release are you using?
