TīmeklisIn a recent note in the Bulletin, Murphy [5] gave a short proof that for complex m × n matrices A and B, r ( A + B )= r ( A )+r ( B) if the rows of A are orthogonal to the rows of B and the columns of A are orthogonal to the columns of B. His proof was elegant and simple, an improvement on an earlier proof of the same result by Meyer [4]. Tīmeklis题目 矩阵A,B满足 A+B=AB ,如何证明 rank(A)=rank(B)? 证明:由条件可得.
