I defined my own AltGamma[z], how to stop 'matica using its Gamma[z] rules?

Simon Jackson

I've defined an entire Gamma function. It does not match the negative axis of the Euler Gamma[z], and so the transforms of the Gamma built in are not appropriate. How do I disable the built in rules for Gamma[z], so that I can actually do maths using my functional definition?

You don't want to redefine Gamma. Changing it might break anything built on top of it. Having warned about that, you can change Gamma with the Unprotect and Protect expressions. For example:

Unprotect[Gamma]
Gamma[x_] := x*2
Protect[Gamma]

Frank Kampas's suggestion is the correct one.

I suggest you call your function myGamma and use it that way. The built-in function might be used for other calculations.
