摘要 本文给出由一个矩阵 CQFs派生出许多新的矩阵 CQFs的方法 .指出若一个 CQFs满足完全重构条件 ,则派出生出的 CQFs也满足完全重构条件 .也建立了由低阶矩阵 CQFs派生出高阶矩阵 CQFs的方法 . The paper shows,many new matrix CQFs can be constructed from the matrix CQFs by a new method.If perfect reconstuction condition of the original CQFs satisfied,then the newly-constructed CQFs are also perfectly-reconstructed.Eurther,a set of rules for deriving higher matrix CQFs from a lower one are established.
