| Post subject: | Problem when calling gamma function from gammafunc.cpp |
Hi folks, I have a problem when compiling a library that uses the alglib to do some calculations. I have implemented a function to calculate the inverse of Student's cumulative distribution (that I will call tinv). To do so I'm using the invincompletebeta function, which makes use of the gamma function implemented in the gammafunc.cpp file. The problem arises when I call the tinv function and the gamma function from matchalls.h is called (which actually is the natural logarithm of the gamma function) instead of the alglib gamma function. Thus, I end up with some wrong results in my calculations. I would like to know if somebody knows why this is happening and how I could solve this without having to change the alglib source-code. Thanks in advance, C?cero Neves |

Hi, I saw in the bug track tool that this problem was already detected and solved under the ID 0000360 . My doubt now is: Is there some way I can find this fixed release or I will have to wait until the next oficial release of the lib? Regards, C?cero Neves |

I can send development version of new release to your e-mail. Do you need invincompletebeta() only? |

Hello Bochkanov, Currently I am explicitily calling only the invincompletebeta and the kmeansgenerate function. I don't know for sure but I think that only the invincompletebeta will be enough. Best regards, |
