多元非线性函数极值的通用数值解法

An universal numerical algorithm of extremum for multivariate nonlinear function

研究一种多变量非线性函数极值的通用数值解法,并将这种算法应用于石英晶振热敏网络温度补偿系统中.与传统的算法比较,该方法需要的条件十分宽松,无需求解多元非线性方程组,所以推导过程简单,且收敛快.

An universal numerical algorithm of extremum for multivariate nonlinear function is discussed, and is used in the calculate system of compensation for thermistor net. In comparison with the traditional algorithm, it needs lesser conditions. And it＇ s more simple because it doesn＇t needs to solution the nonlinear equations,while it converge faster.
