The chebyshev basis
網頁More polynomials (with more bases) ¶. NumPy also has a more sophisticated polynomial interface, which supports e.g. the Chebyshev basis. Example using polynomials in Chebyshev basis, for polynomials in range [-1, 1]: The Chebyshev polynomials have some advantages in interpolation. 1.4.4.2. 網頁Abstract In this paper, the Chebyshev cardinal functions together with the extended Chebyshev cardinal wavelets are mutually utilized to generate a computational method for solving time fractional coupled Klein–Gordon–Schrödinger equations. By employing the ...

網頁Abstract In this paper, we derive a matrix of transformation of Chebyshev polynomials of the first kind into Bernstein polynomials and vice versa. We also study the stability of these linear maps and show that the Chebyshev–Bernstein basis conversion is remarkably well-conditioned, allowing one to combine the superior least-squares performance of …
