已知矩阵A=，则r(A)= ./ananas/latex/p/807727
举一反三
- 若A是矩阵，B是矩阵,且AB=O，则必有r(B)+r(A)______./ananas/latex/p/111984/ananas/latex/p/112245/ananas/latex/p/1237
- 已知矩阵A=，当a=( )时，矩阵A的秩r(A)=2. /ananas/latex/p/437407
- 7.已知是实对称阵A的3个特征值，且对应于的特征向量分别为 则矩阵A=，则B矩阵中的各个元素 , , ; , , ; , , ./ananas/latex/p/404201/ananas/latex/p/404202/ananas/latex/p/404203/ananas/latex/p/2210847/ananas/latex/p/2210854/ananas/latex/p/2210858/ananas/latex/p/2210861/ananas/latex/p/2210863/ananas/latex/p/2210865/ananas/latex/p/2210869/ananas/latex/p/2210872/ananas/latex/p/2210875/ananas/latex/p/2210877
