给我一段ceemdan-wpt的matlab代码

以下是一段ceemdan-wpt的matlab代码的示例：

%% Load and preprocess data
load('signal.mat'); % Load signal
Fs = 5000; % Sampling frequency
t = 0:1/Fs:(length(signal)-1)/Fs; % Time vector
signal = signal - mean(signal); % Remove DC offset

%% Perform decomposition and reconstruction using CEEMDAN and WPT
nIMFs = 6; % Number of IMFs to extract
IMFs = ceemdan(signal, nIMFs); % Perform CEEMDAN decomposition
alpha = 1; % Alpha value for wavelet packet transform
nLevels = 6; % Number of levels for wavelet packet transform
reconSignal = ceemdan_wpt_recon(IMFs, alpha, nLevels); % Perform reconstruction

%% Plot results
figure;
subplot(2,1,1); plot(t,signal); title('Original Signal');
subplot(2,1,2); plot(t,reconSignal); title('CEEMDAN-WPT Reconstructed Signal');xlabel('Time (s)');ylabel('Amplitude');

注意：这只是一个简单的示例代码，请根据您的具体需求进行修改和调整。
