假设有矩阵A_{2 \times3} = \left[ \begin{matrix} 1 & 4& 5\\ 2 & 8& 10\ \end{matrix} \right] \ \\ 我们一看就知道,第二行是第一行的两倍,rank = 1, 这个矩阵可以写成 A_{2 \times3} = \left[ \begin{matrix} 1 & 4& 5\\ 2 & 8& 10\ \end{matrix} \right] \ = \left...
1 英语原意 矩阵的秩：Matrix Rank 2 英文解释 The rank of Matrix is how many of the rows are "unique": not made of other rows. (Same for columns.)Example 矩阵的秩 Matrix Rank 是什么意思？本意明明是等级的意思，但翻译成中文之后却变了味 The second row is just 3 times the first row. ...
而rank\Big(\left[ \begin{matrix} I_n & -B \\ A & O \end{matrix} \right]\Big)\ge rank(A)+rank(B) ,因此原命题成立。 证明二(方程组的观点): 记B=(\beta_1,\beta_2,...,\beta_n) ,其中 \beta_i(i=1,2,...,n) 是B 的列向量。那么 \\AB=(A\beta_1, A\beta_2,......
