計算矩陣連乘積 問題描述 在科學計算中經常要計算矩陣的乘積。矩陣A和B可乘的條件是矩陣A的列數等于矩陣B的行數。若A是一個p×q的矩陣，B是一個q×r的矩陣，則其乘積C=AB是一個p×r的矩陣。

matlab 自適應遺傳算法源程序，用到了G-S正交化分解，大家可以用QR分解做一下，應該會使程序更簡單一點．

平均因子分解法，適用于正定矩陣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 triangular (that is, it has all zeros below the diagonal). It seems that the assumption of positive definiteness is necessary. Actually, it is "positive definite" which guarantees the existence of such kind of decomposition.

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 factorization of the transition probability which allows the Rao-Blackwellization of the filtering step. Both simplifications can be implemented using the coarse projective integration framework. The resulting particle filter is faster and has smaller variance than the particle filter based on the original system. The convergence of the new particle filter to the analytical filter for the original system is proved and some numerical results are provided.

％ 奇異值分解 (sigular value decomposition,SVD) 是另一種正交矩陣分解法；SVD是最可靠的分解法， ％ 但是它比QR 分解法要花上近十倍的計算時間。[U,S,V]=svd(A)，其中U和V代表二個相互正交矩陣， ％ 而S代表一對角矩陣。 和QR分解法相同者， 原矩陣A不必為正方矩陣。 ％ 使用SVD分解法的用途是解最小平方誤差法和數據壓縮。用svd分解法解線性方程組，在Quke2中就用這個來計算圖形信息，性能相當的好。在計算線性方程組時，一些不能分解的矩陣或者嚴重病態矩陣的線性方程都能很好的得到解
