I see that @James mentioned that he wrote the code using Octave. The Octave hex2num() supports passing a class as the second parameter, but MATLAB does not.
I think you can change the hex2udp line
udp.(fields{fn}) = uint16(sscanf(udp.(fields{fn}), '%x'));
This would possibly have slightly different behaviour in cases where the input somehow had spaces or non-hex characters instead of the expect hex output; I do not have access to Octave to test its behaviour in detail (and there is the big question of what would be most reasonable to have happen in that circumstance.)

There is no such feature as of now, but it might be considered for a future release. However, 'pcap2matlab' is one of the several submissions in MATLAB File Exchange on MATLAB Central which is a forum for our product users to interact, exchange information and knowledge, without MathWorks' involvement. Feel free to contact the author of this submission directly for specific questions about the implementation.
Here's the link to the file:
