FORTRAN Routines for Spectral methods. Here is a collection of 80 FORTRAN routines that written in 1993. They deal with standard families of orthogonal polynomials (Legendre, Chebyshev and, more in general, Jacobi; Laguerre and Hermite) and allow the computation of zeros, quadrature weights, transformation from Fourier coefficients to point-values (and viceversa), evaluation of norms, differentiation.
