Description: 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）-procedure used to upgrade Method second generation wavelet transform I use a non-integer-order wavelet transform domain when used, the first step out go backward transformation : split and forecast updates; Anti-Transform : Update, forecasting, consolidations only one (which can be multi-storey, but each floor and update the forecast equation different) Platform: |
