That's not the correct definition of the concept of "weighted average". Instead, it's rather the average product of two data vectors x and w.

But in tests #7 and #8 too, the subscript index is neither a positive integer nor a logical value; so why does it not lead to the same subscript indexing error that invokes the 'catch' statement?

However, on closer inspection, I feel there's still something missing in the explanation. If it's merely a matter of failed/absent variable assignment to a comma-separated list, then why does this code still successfully enter into the catch statement in tests #3 and #6 (in which input x is a non-integer number)?

Thanks, Peng Liu, for your concise explanation! It greatly helps in improving my understanding of cell variables/comma-separated lists as well as the try-catch function and error handling, which are topics that I still find quite complicated; but your comment explains it very clearly and easily! :-)
