Ample numerical results are presented to illustrate the computational efficiency and accuracy of our algo-rithm. 1. Introduction WebJan 31, 2024 · However, every vector of Chebyshev–Lobatto samples \(f(x_{j})\) of a function is, through the magic of a Fast Cosine Transform (FCT) or a Matrix-Multiplication Transform (MMT), equivalent to a vector of Chebyshev coefficients. The Chebyshev interpolant can be evaluated at any x that we please. tepung beras dapat diolah menjadi
