📊 Represent the A59 spectrum as a function using MATLAB

[programarivm]

Chess\SanSignal returns the oscillations of all evaluation features both in the time domain and the spectrum domain:

• All Oscillations of a Game

The spectrum domain can be converted back to a chess game with the help of a ChesslaBlab algorithm.

If the so-called chess spectrum can be converted to a function, then it may be processed as a signal with mathematical tools like the Discrete Fourier Transform (DFT) to hopefully find patterns that can't be seen via direct observation.
