rms() is part of the signal processing toolbox. Do you have SPT?

If not, you can always define your own function that does the same thing (for the specific syntax being used).

As an anonymous function within the existing code:

rms = @(x) sqrt(mean(x.^2));

Or as an external function file like the one attached. SPT rms() supports other things which don't appear to be used in your case, so this is just simplified implementation.
