The authors construct a rank diminishing algorithm for matrices and adapt it for application to Lagrange interpolation polynomials L sub n0 fx of degree or n-1. In r steps the authors arrive at the polynomials L sub nr fx of degree n-r-1, which share many approximation theoretic properties with Lagrange interpolation polynomials. Author
