What is RDFS ?

Regressive Discrete Fourier Series

The reducer discrete Fourier series (CDFs) used in Applied Mathematics ، is actually an expansion of the discrete Fourier transform. In this expansion, the conversion coefficients are calculated using the same method as the least squares and the selected periodicity. The series was first introduced by aruda. This series can be used to smooth (smooth) information in one and two dimensions.
