Functions

double AlgGammaLog (double x, AlgError *dstErr)
 Computes the log gamma function log(Gamma(x)), ie exp(AlgGammaLog(n + 1)) = n!. This function is based on the function gammln(): Press W. H., Teukolsky S. A., Vetterling W. T. and Flannery B. P, Numerical Recipies in C, 1992, CUP.
double AlgGammaP (double a, double x, AlgError *dstErr)
 Computes the incomplete gamma function P(a,x), which has the limiting values P(a,0) = 0, P(a, oo) = 1.. This function is based on the function gammp(): Press W. H., Teukolsky S. A., Vetterling W. T. and Flannery B. P, Numerical Recipies in C, 1992, CUP.
