Why does str2num work for anonymous function?

Peng Liu on 18 Dec 2018

Don't be confused by the name "str2num", which might give you a wrong impression that this function only works for str to number conversion. In fact, it is more powerful because it supports evaluation of any valid string or character represented MATLAB expressions in much the same way eval does. The underlying implementation of str2num is indeed based on eval. Check the documentation and source file for more details.

Cheating a bit. I believe test suite need some "try...catch" to prevent such behaviour.

nevertheless, didn't see this coming. never expected that kinda structure would work.
