%%?Boundary?detection
%?We?compute?the?Fourier?transform?of?f
ff=fft（f）;
%?We?extract?the?boundaries?of?Fourier?segments
boundaries?=?EWT_Boundaries_Detect（abs（ff（1:round（length（ff）/2）））params）;
boundaries?=?boundaries*pi/round（length（ff）/2）;

%%?Filtering
%?We?extend?the?signal?by?miroring?to?deal?with?the?boundaries
