此程序用提升法实现第二代小波变换

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）-This procedure achieved by lifting the second generation wavelet transform with a non-integer order wavelet transform time-domain realization of transformation steps, then over are: split, predict, update　inverse transform: Update, forecasting, consolidation only a layer of ( can be multi-layer, and each prediction and update equations are different)
