Evaluation of polynomials

Evaluation of the polynomials should be done by normalizing the data as indicated above. Something like:

  const real8 const real8 minL = master.originalwindow.linelo;
  const real8 maxL = master.originalwindow.linehi;
  const real8 minL = master.originalwindow.pixlo; 
  const real8 maxL = master.originalwindow.pixhi; 
  matrixreal4(N,1) l\_axis = linenumbers; 
  normalize(l\_axis); 
  matrixreal4 f = polyval(l\_axis, p\_axis, coefficients, [degree]);

NOTE: It is faster to evaluate a polynomial on a grid than point by point.
