Webe其实就是单位时间内，持续的翻倍增长所能达到的极限值。 比如：细胞分裂是一个细胞分裂为两个细胞，这就是翻倍增长（即取100%），那么就要问了：假如细胞连续分裂，分裂时长为一天，那么1个细胞在1天结束那刻是几个细胞了呢？ Web答案解析 查看更多优质解析 举报 A-λE =-λ 0 1a 1-λ b1 0 -λ= (1-λ) [ (-λ)^2-1]= (1-λ)^2 (1+λ).所以A的特征值为1,1,-1.因为A有3个线性无关的特征向量,所以属于特征值1的线性无关的特 …

Web最好的办法是用矢量线性组合的方式：我们首先将 A 通过类似Gauss-Jordan消元的方式化为简化的行阶梯矩阵；然后，我们让自由变量巧妙取值得到 Ax=0 “特殊形式”的解，这些解的线性组合就构成了整个零空间。 矩阵 A=\begin {bmatrix}1&2&2&2\\ 2&4&6&8\\ 3&6&8&10 \end {bmatrix} ，通过消元变为 U ：
