變點數-
( 2 ) in the study of multivariate phenomena, each time variable should possess its own scaling parameter in order to allow maximal flexibility in time - frequency. the notion of multifrequency multifunction wavelets, to be introduced, is based on this point of view. multifrequency wavelets, via directional multiresolution analysis, generated by a single function is extended to multifrequency multifunction wavelets generated by a finite number of functions
( 2 )在研究多變量問題時,為了使時頻分析具有最大的靈活性,要求每個時間變量都有它自己的尺度參數,鑒於此,本文從尺度函數構成正交基或riesz基出發,把一維多函數小波推廣到二維多頻率多函數小波,解決了構造正交或雙正交多頻率多函數小波所需要的理論依據。
