Undead anatomy and Monstrous Physique.

Hi everybody.
I have a question about the above spells.

If I am a magus using these spells does my weapon resize with me, does it remain unaffected or is it a similar set up to wild shape?

I'm running with the idea that my weapon doesn't change as it doesn't say anything about it. What do people think?

The answers you seek are all in the description of the polymorph subschool of transmutation on pages 211 and 212 of the Core Rulebook.

Core Rules wrote:

When you cast a polymorph spell that changes you into a creature of the animal, dragon, elemental, magical beast, plant, or vermin type, all of your gear melds into your body. Items that provide constant bonuses and do not need to be activated continue to function while melded in this way (with the exception of armor and shield bonuses, which cease to function). Items that require activation cannot be used while you maintain that form. While in such a form, you cannot cast any spells that require material components (unless you have the Eschew Materials or Natural Spell feat), and can only cast spells with somatic or verbal components if the form you choose has the capability to make such movements or speak, such as a dragon. Other polymorph spells might be subject to this restriction as well, if they change you into a form that is unlike your original form (subject to GM discretion). If your new form does not cause your equipment to meld into your form, the equipment resizes to match your new size.

All emphasis mine.
