matlab中求解线性方程组的源代码
模糊数学在工程技术、管理科学、金融工程等领域应用中的很多问题都可以用模糊方程和模糊线性系统来描述。但是,实现模糊方程和模糊线性系统的求解十分困难,对求解方法的研究一直以来都是重点,也是难点。无论从理论研究还是从实际应用的角度来说,对模糊方程和模糊线性系统的求解研究都具有重要意义。本文针对传统方法求解模糊方程和模糊线性系统在模糊数运算、隶属函数解析表示、模糊解判定等方面存在的困难,借助模糊结构元理论,相应地提出了一套模糊方程和模糊线性系统的求解方法。首先,利用两个单调函数的自反单调变换构造了等式限定算子,推广了等式限定运算,处理了存在负模糊情况下关于乘法运算的不可逆问题。并将等式限
