Logbeta
Logarithm of the beta function of a real argument.
 
Loading        LOADSUB ALL FROM "GAMMA.HTS"
or LOADSUB FROM "MATHLIB.HTS"
 
Usage                REAL A,B,Y
Y=FNLogbeta(A,B)
 
Description                
FNLogbeta returns the value of the logarithm of the beta function of a and b, log[B(a,b)]. B(a,b) is defined as (a)(b)/(a+b) (see Gamma). B(a,b) is only defined for a > 0 and b > 0.
 
Errors                
FNLogbeta causes an HTBasic error if its arguments are not both of type REAL or if either a or b is negative or zero.
