GEGENBAUER_CC
Gegenbauer Integral of a Function
GEGENBAUER_CC
is a C library which
uses a ClenshawCurtis approach to approximate the integral of a
function f(x) with a Gegenbauer weight.
The Gegenbauer integral of a function f(x) is:
value = integral ( 1 <= x <= + 1 ) ( 1  x^2 )^(lambda1/2) * f(x) dx
where 0.5 < lambda.
