This leads to an algorithm that runs in [Math Processing Error]O(n3/4) time and uses [Math Processing Error]O(n) memory. Algorithm D can be derived from formula (5) by splitting the first sum at [Math Processing Error]v(n)=⌊n(⌊n23⌋+1)⌋ as follows: [Math Processing ...
对于一个数列{ a}，如果任意相邻两项之差为一个常数，那么该数列为等差数列，且称这一定值差为公差,记为 d ；从第一项 a₁到第n项 aₙ的总和，记为Sₙ 。那么 ， 通项公式为 ，其求法很重要，利用了“叠加原理”的思想：将以上 n-1 个式子相加， 便会接连消去很多相关的项 ，最终等式左边余下...

对角阵的行列式等于对角线上元素相乘,这可以由性质3a)得到, \left| \begin{matrix} a&0 \\ 0&d \end{matrix} \right|=a\left| \begin{matrix} 1&0 \\ 0&d \end{matrix} \right|=ad\left| \begin{matrix} 1&0 \\ 0&1 \end{matrix} \right|=ad ,于是三角阵的行列式也等于对角线上元素相乘...
