摘要
借助于矩阵对的标准相关分解(canonical correlation decomposition)及矩阵A的满秩分解,得到了秩等式rank( A- AN( M^T AN)^- M^T A) = rank( A)- rank( AN( M^T AN)^- M^T A)成立的一个充分必要条件。
In this paper, by applying the canonical correlation decomposition of the matrix pair and the full rank decomposition of the matrix A, we obtain a necessary and sufficient condition for the validity of the rank subtractivity formula rank(A -AN(MTAN) - MTA) = rank(A) - rank(AN(MT AN) - MT A).
