计算矩阵连乘积 问题描述 在科学计算中经常要计算矩阵的乘积。矩阵A和B可乘的条件是矩阵A的列数等于矩阵B的行数。若A是一个p×q的矩阵，B是一个q×r的矩阵，则其乘积C=AB是一个p×r的矩阵。

研究生期间上《数值计算方法》课的作业，所有代码都是C语言实现并调试通过，现在上传为大家服务。这是QR算法

一些矩阵运算的C代码实现：矩阵一般运算，以及求逆，QR分解，householder变化，LDU, LU分解

matlab 自适应遗传算法源程序，用到了G-S正交化分解，大家可以用QR分解做一下，应该会使程序更简单一点．

平均因子分解法，适用于正定矩阵First, let s recall the definition of the Cholesky decomposition: Given a symmetric positive definite square matrix X, the Cholesky decomposition of X is the factorization X=U U, where U is the square root matrix of X, and satisfies: (1) U U = X (2) U is upper triangul ...

数学，好似后的变换，QR分解等解场系数微分方程的程序

We present a particle filter construction for a system that exhibits time-scale separation. The separation of time-scales allows two simplifications that we exploit: i) The use of the averaging principle for the dimensional reduction of the system needed to solve for each particle and ii) the factor ...

％ 奇异值分解 (sigular value decomposition,SVD) 是另一种正交矩阵分解法；SVD是最可靠的分解法， ％ 但是它比QR 分解法要花上近十倍的计算时间。[U,S,V]=svd(A)，其中U和V代表二个相互正交矩阵， ％ 而S代表一对角矩阵。 和QR分解法相同者， 原矩阵A不必为正方矩阵。 ％ 使用SVD分解法的用途是解最小平方误差法和数据压 ...
