差商 meaning in English
difference quotient
Examples
- Expressing matrix function by divide difference of eigenvalues
用特征值的差商表示矩阵函数 - A type of super convergent formulas for numerical divided differences
一类超收敛数值差商公式研究 - The explicit formula of general divided difference with multiplicity knots
一般有重差商的显式公式 - In chapter two , we put forward an iteration ( 2 . 1 . 1 ) in which the first derivative and the first divided difference are only calculated in each step
1 . 1 )与另两个也仅含一阶导数和一阶差商的算法及两步newton迭代的收敛阶 - Relative difference quotient algorithm is strong in local search , while genetic algorithm with a parallel operation is highly effective in global search
相对差商算法局部搜索能力强，而遗传算法具有较强的全局搜索性，发挥两者的优势，提出组合遗传算法。
