Various kinds of Gamma Functions.
The Gamma module provides several generic and special Gamma functions derived from the SLATEC Library.
- Gamma.compl : complete Gamma function
- Gamma.ln : logarithm of the absolute value of the Gamma function
- Gamma.recip : reciprocal of the Gamma function
- Gamma.incompl : incomplete Gamma function
- Gamma.comp_incompl : complementary incomplete Gamma function
- Gamma.tricomi : Tricomi's form of the incomplete Gamma function
[ y:float ] = Gamma.compl (x:float)
[ y:float ] = Gamma.ln (x:float)
[ y:float ] = Gamma.recip (x:float)
[ y:float ] = Gamma.incompl (a:float) (x:float)
[ y:float ] = Gamma.comp_incompl (a:float) (x:float)
[ y:float ] = Gamma.tricomi (a:float) (x:float)
Examples:
[] Gamma.ln 0.1 ;;
- : float = 2.25271265173
[] Gamma.compl 1.0;;
- : float = 1
[] Gamma.incompl 1.0 5.0;;
- : float = 0.993262053001
