21 This function finds some uses in statistical distributions: it
22 computes the partial derivative with respect to /x/ of the incomplete
23 beta function __ibeta.
25 [equation derivative2]
27 The return type of this function is computed using the __arg_pomotion_rules
28 when T1, T2 and T3 are different types.
34 Almost identical to the incomplete beta function __ibeta.
38 This function just expose some of the internals of the incomplete
39 beta function __ibeta: refer to the documentation for that function
