【摘要】 利用边界矩阵和区间算法理论,讨论超定系统奇异解的数值解法及其可信验证.提出一种新算法,该算法输出一个近似解及其相应的误差界,使得在近似解的误差界范围内必存在一个精确解.更多还原

【Abstract】 We studied the numerical method and verification for singular points of overdetermined nonlinear equations.And we proposed an algorithm on the basis of the bordered system and interval theory.It outputs an approximate solution and its error bound so as to make an exact solution exist within this computed bounds.更多还原
