求解非线性方程组的方法研究。非线性代数方程组求解是一个基本而又重要的问题,因为在工程实践、经济学、侪息安全和动力学等方面有大量的实际问题最终转化为代数方程组,而非线性方程组的求解方法长期以来一直是工程应用和数值计算中重要的研究内容。-Research method for solving nonlinear equations. Solving nonlinear algebraic equations is a basic and important issue, because a large number of practical problems in engineering practice, economics, peer-bearing safety and dynamics eventually transformed into algebraic equations, and nonlinear equations solving method has long been important research in engineering applications and numerical calculations.
