  19 [h4 Description]
  20
  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]
  26
  27 The return type of this function is computed using the __arg_promotion_rules
  28 when T1, T2 and T3 are different types.

  32 [h4 Accuracy]
  33
  34 Almost identical to the incomplete beta function __ibeta.
  35
  36 [h4 Implementation]
  37
  38 This function just expose some of the internals of the incomplete
  39 beta function __ibeta: refer to the documentation for that function
  40 for more information.
