banded matrix

基本解釋

In his PNAS paper, Strang describes a new technique for breaking a banded matrix up into simpler matrices — matrices with fewer bands.
在他的科學(xué)院院刊的那篇論文中，Strang描述了一種新的把帶狀矩陣分解成幾個簡單的，有更少條帶的矩陣的方法。
For a general banded matrix, discuss the sparsity pattern of the Q and R matrices from the QR decomposition of symmetric and non-symmetric tridiagonal matrices.
對于一般的帶狀矩陣，詳述對對稱與非對稱三對角化矩陣做QR分解后，Q矩陣與R矩陣的稀疏元素分布型態(tài)。
