此程序用提升法实现第二代小波变换

％％ 我用的是非整数阶小波变换

％％ 采用时域实现,步骤先列后行

％％ 正变换：分裂，预测，更新；

％％ 反变换：更新，预测，合并

％％ 只做一层（可以多层，而且每层的预测和更新方程不同）-the procedure used to upgrade method is the second generation wavelet transform%% I use a non-integer-order wavelet transform%% using time domain achieved, steps out first go backward%% transformation : split and forecast updates; %% inverse transformation : Update, forecasting, %% off with a layer (which can be multi-storey, but the typical forecast and updating different equation)
