[Help-gsl] incomplete gamma functions

[Robin Hankin]

Dear All

Functions gsl_sf_gamma_inc_Q(a,x) and gsl_sf_gamma_incP(a,x)
calculate the upper and lower normalized incomplete gamma functions
respectively.

Function gsl_sf_gamma_inc(a,x) calculates the un-normalized upper
incomplete gamma function.

There doesn't seem to be an un-normalized lower incomplete
gamma function.

Could the developers add writing such a function to the To-Do list  
please?


best wishes and thanks for a splendid library
