6608 :: Incomplete gamma function in Nim or it's 3rd party libraries

• wiltzutm (orginal) [2020-07-28T10:21:08+02:00] view original

  Hello everyone! I need the incomplete gamma function in my code, but I cannot find it neither from standard libraries nor 3rd party packages. Does anyone have any idea if it's implemented in some nim package? I know there's the complete gamma function in standard math.

  How about wrapping some existing C library? Any lib suggestions? Althought I'm not sure I'm able to wrap it myself because I'm still relatively new in Nim and typed languages in general...

  Best regards and thank you for your time.

  I don't know the gammafunction but maybe in math.h?

  Yes I communicated it badly in my post. I know of the existence of the math.h gamma function. Problem is that it's the complete gamma function eg. usually called just gamma function. I need the INCOMPLETE and actually more specifically the lower incomplete version of it. This is actually the function I need: https://se.mathworks.com/help/matlab/ref/gammainc.html

  I was a bit too hasty writing the post. In the end I was able to circumvent the problem altogether. Sorry for the noise. Also I'm still convinced that a special functions lib like python's scipy.special would be beneficial not as a std lib but some 3rd party implementation.
