GEGENBAUER_RULE is a C++ program which generates a specific Gauss-Gegenbauer quadrature rule, based on user input.
The rule is written to three files for easy use as input to other programs.
The Gauss-Gegenbauer quadrature rule is used as follows:
Integral ( A <= x <= B ) ((x-A)(B-X))^alpha f(x) dxis to be approximated by
Sum ( 1 <= i <= order ) w(i) * f(x(i))where alpha is a real parameter greater than -1.
