NormFunction is an option for functions such as FindFit and NDSolve which gives a function to be minimized in generating results.

QGamma[z, q] gives the q-gamma function \[CapitalGamma]_q (z).

lhs -> rhs or lhs -> rhs represents a rule that transforms lhs to rhs.

When you write a program in Mathematica, you should always try to set it up so that its parts are as independent as possible. In this way, the program will be easier for you ...
