Note that the user is not free to choose the interpolation points. Instead, the function f (x) will be evaluated at points chosen by the algorithm. In the standard case, in which the interpolation interval is [-1,+1], WebMay 2, 2014 · Just use the product of one-dimensional Chebyshev grids, that is, the set of all points ( x i, y j) where x i and y j run over 1D Chebyshev nodes independently. For example, this library uses product … WebOct 28, 2024 · And yes, you have incorporated the order of the Chebyshev polynomial: as the order is arbitrarily chosen (e.g. you can have a second ordered Chebyshev polynomial p2 (x), third order p3 (x), etc.), your function argument n in the calculation of Chebyshev nodes is the order of the polynomial.
