Hi, I would like some information. How much the special functions implementation is targeted to the evaluation of statistical quantities over the different distributions ? Is the special functions implentation enough general to be usable as a standalone library ? If so, why not split the math toolkit into two libraries ? A special funcion library, merged with the special functions by Hubert Holin and Eric Ford, and a statistics library including distributions and operation over them. If their code is already uncoupled, this would require only a documentation splitting. How much the special functions in the math toolkit conform to the ISO C++09 standard proposal for a special function library ?
