emd分解程序代码,里面有详细介绍,请下载使用(function imf = emd(x)
% Empiricial Mode Decomposition (Hilbert-Huang Transform)
% imf = emd(x)
% Func : findpeaks
x = transpose(x(:));
imf = [];
while ~ismonotonic(x)
x1 = x;
sd = Inf;
while (sd > 0.1) || ~isimf(x1)
s1 = getspline(x1);
s2 = -getspline(-x1);
x2 = x1-(s1+s2)/2;
sd = sum((x1-x2).^2)/sum(x1.^2);
x1 = x2;
end
imf{end+1} = x1;
x = x-x1;
end
imf{end+1} = x;)
