matlab提取文件要素代码注意 目前暂缓开发,所有软件均可用。 并非所有功能都正常。 克里洛夫·基特(KrylovKit) 该存储库包含Matlab文件,通过对递归矩阵的QR分解表示进行运算,以处理标准,扩展和有理Krylov序列。 这种表示允许在三种不同类型的Krylov递归之间进行直接转换,并为隐式重启迭代提供了统一的方法。 还提供了一些用于处理块Krylov迭代的代码。 标准克雷洛夫 在标准Krylov算法中,Krylov子空间是用Arnoldi方法构造的,该方法将矩阵向量乘积与矩阵A正交计算出的向量正交化,并且Arnoldi递归成立: A * V i = V i + 1 * H i 。 V i + 1的列跨度K i + 1 (A,v)= span(v,A v,A 2 v,...,A i v)。 矩阵H i是i + 1 xi不可归约的上Hessenberg矩阵,该矩阵允许QR分解以核变换的浓缩,下降模式进行。 核心变换是用于在矩阵中引入零的2 x 2矩阵,此处使用的所有核心变换都是一元的。 扩展的克雷洛夫 在扩展的Krylov算法中,Krylov子空间的丰富之处还包括通过求解具
