WebThis video demonstrates how to use the FFTW library in order to compute the 1-D type-II DCT (discrete cosine transform) and its IDCT (inverse discrete cosine... WebMar 5, 2024 · If available through fftw3, the DCT-II/FFT is used to compute coefficients for a Chebyshev interpolation. Other interpolation methods for arbitrary Cartesian grids are also provided, a piecewise multilin-ear, and the Floater-Hormann barycenter method. For scattered data polyharmonic splines with a linear term
