Uniform Filter Bank 1.0

This function can be used to design a uniform filter bank (with M analysis and M synthesis filters) so that the perfect reconstruction is almost achieved. The method is based on the optimization technique proposed in [1].M= Number of subbandsm= A positive integer[analysis_filters,synthesis_filters] are analysis and synthesis filters'coefficients of the designed filter bank (each row is devoted to one filter). Thelength of all filters is 2*(m*M). The amplitude response of the analysis filters will be shown at the end.Example:[analysis_filters,synthesis_filters]=PR_Nguyen(5,4)Reference:[1] T.Q.
