Determination of the Zeros of a Linear Combination of Chebyshev Polynomials
J. A. Grant, A. GHIATIS · IMA Journal of Numerical Analysis · 1983
Consideration is given to the ways in which algorithms for finding the zeros of polynomials expressed in the monomial basis may be modified to find the zeros of polynomials expressed in the Chebyshev basis. The extension to other bases is indicated.
