Gauss-Jacobi quadrature
No License
Ever wonder how the weights and abscissae are calculated for the numerical conversion from radiance to flux? The long and the short of it is that Gauss-Jacobi quadrature determines the weights and abscissae which is similar to Gaussian for low-point quadrature but differs substantially for high-point quadrature. This program follows Abramowitz and Stegum to produce the roots of a Jacobi polynomial from which both weights and abscissae are determined.
