[section:beta_derivative Derivative of the Incomplete Beta Function]
[h4 Synopsis]
``
#include <boost/math/special_functions/beta.hpp>
``
namespace boost{ namespace math{
template <class T1, class T2, class T3>
``__sf_result`` ibeta_derivative(T1 a, T2 b, T3 x);
template <class T1, class T2, class T3, class ``__Policy``>
``__sf_result`` ibeta_derivative(T1 a, T2 b, T3 x, const ``__Policy``&);
}} // namespaces
[h4 Description]
This function finds some uses in statistical distributions: it
computes the partial derivative with respect to /x/ of the incomplete
beta function __ibeta.
[equation derivative2]
The return type of this function is computed using the __arg_promotion_rules
when T1, T2 and T3 are different types.
[optional_policy]
[h4 Accuracy]
Almost identical to the incomplete beta function __ibeta.
[h4 Implementation]
This function just expose some of the internals of the incomplete
beta function __ibeta: refer to the documentation for that function
for more information.
