说明：  此程序是运用music方法估计功率谱，并实现了信号还原。(This program adopts the mathod of music psd to estimate the powerdensity,and get the original signal.)

说明：  matlab的一些程序的基础，希望对有需要的人有些帮助。(The basis of some programs in MATLAB is expected to be helpful to those in need.)

里面是几个小波构造的程序，Daubechies小波基的构造，采用多孔trous算法(undecimated wavelet transform)实现小波变换 。(inside several wavelet construction procedures Daubechies wavelet construction, using porous trous algorithm (undecimated wavelet transform) achieve wavelet transform.)

It should be noted that there is still room to improve the speed and the memory usage of the algorithms, using for instance displacement structure algorithms for the RQ decomposition and Lanczos algorithms for the SVD.

对于时间序列模型建立ARMA预测模型，可对未来值进行预报。(For the time series model, the ARMA prediction model is established, and the future value can be forecasted.)
