Debugging Hysdel
Hysdel3 by default traps all errors by a try/catch statement. This, on one hand, saves the user from unnecessary error messages, but on the other hand it may hide the actual cause of the error.
To tell Hysdel3 to use the debugging mode, use the following calling syntax:
>> hysdel3('path/to/source.hys', struct('debug', 1));
