说明：  用于数据预处理的多小波分解与重构程序.其中多小波是采用CL4平衡多小波,所以分解前的预处理是采用等值预滤波器.如果要用别的非平衡多小波,只需替换为相应的预滤波器即可.
(for data pretreatment multiwavelet decomposition and reconstruction process. Multiwavelet which is the Panasonic balance multiwavelets Therefore, the pretreatment before decomposition is the equivalent pre-filter. If you want other non-equilibrium multiwavelets only replacement for the corresponding pre-filter may be.)
