2006-12-01 Thread Paulo Jabardo
Hello, I just released an extension to gsl that computes jacobi polynomials, zeros of jacobi polynomials and several operations related to Gauss-Jacobi quadrature (numerical integration, numerical derivatives and interpolation using the quadrature nodes). The extension can be found at:
