Query: Polynomial regression using trapezoidal rule for computing Legendre
  coefficients   We are presenting a method for computing the Fourier coefficients of a given
polynomial regression by using the trapezoidal rule for numerical integration.
As function basis we use the orthogonal Legendre polynomials. The results are
accurate and stable compared to Forsythe's method.
