Hola! tengo que entender esta funcion para poder pasarla a C++, alguien me podría ayudar a comprenderla??
Gracias, Un Saludo.

function [L,S,T,maxes] = find_landmarks(D,SR,N)
% [L,S,T,maxes] = find_landmarks(D,SR,N)
% Make a set of spectral feature pair landmarks from some audio data
% D is an audio waveform at sampling rate SR
% L returns as a set of landmarks, as rows of a 4-column matrix
% {start-time-col start-freq-row end-freq-row delta-time}
% N is the target hashes-per-sec (approximately; default 5)
% S returns the filtered log-magnitude surface
% T returns the decaying threshold surface
% maxes returns a list of the actual time-frequency peaks extracted.

% REVISED VERSION FINDS PEAKS INCREMENTALLY IN TIME WITH DECAYING THRESHOLD
