Primary definition

Basic definition

Above generic formula cannot directly be used for nonpositive integers a, b, which lead to indeterminate expressions like 0/0. In these cases, it is more necessary to use an equivalent complete definition, presented below.

Complete definition

The function (Subscript[I, z])(a,b) can be equivalently defined through the following generalized hypergeometric function.
