Polynomial approximation of derivatives by the constrained mock-Chebyshev least squares operator

Francesco Dell'Accio, Federico Nudo

The constrained mock-Chebyshev least squares operator is a linear approximation operator based on an equispaced grid of points. Like other polynomial or rational approximation meth…
