    See Allasia and Besenghi (1987b) for the numerical computation of Γ ( a , z ) from (8.6.4) by means of the trapezoidal rule. … DiDonato and Morris (1986) describes an algorithm for computing P ( a , x ) and Q ( a , x ) for a 0 , x 0 , and a + x 0 from the uniform expansions in §8.12. …A numerical inversion procedure is also given for calculating the value of x (with 10S accuracy), when a and P ( a , x ) are specified, based on Newton’s rule (§3.8(ii)). … The computation of γ ( a , z ) and Γ ( a , z ) by means of continued fractions is described in Jones and Thron (1985) and Gautschi (1979b, §§4.3, 5). … Expansions involving incomplete gamma functions often require the generation of sequences P ( a + n , x ) , Q ( a + n , x ) , or γ * ( a + n , x ) for fixed a and n = 0 , 1 , 2 , . …
