STRSCNE
给出变量的上下边界、初值和代价函数,能够搜索代价函数最小值时的变量取值。属于带约束的优化算法,可以用来求算非线性方程组。(STRSCNE is a Matlab code for constrained nonlinear systems of equations
F(x)=0 l<=x<=u
where F: R^n--> R^n, l and u are vectors of dimension n. Non-existent lower and upper bounds, i.e.
entries of l and u equal to minus o plus infinity, are allowed.
The algorithm is a globally convergent procedure that combines Newton method and an elliptical trust-region approach. The elliptical trust-region is defined employing a scaling diagonal matrix D
and the trust-region subproblem is approximately solved by the dogleg method. Only strictly feasible iterates are generated.
Various input/output options are provided, and we refer to the code itself for further documentation.

QR-decomposition
QR分解法是目前求一般矩阵全部特征值的最有效并广泛应用的方法,一般矩阵先经过正交相似变化成为Hessenberg矩阵,然后再应用QR方法求特征值和特征向量。它是将矩阵分解成一个正规正交矩阵Q与上三角形矩阵R,所以称为QR分解法,(QR decomposition
