因此，工程师们才对拥有带状逆阵的带状矩阵感兴趣，然而那些是什么样的矩阵却并非显而易见。
So engineers are interested in banded matrices with banded inverses, but which matrices those are is by no means obvious.
那是傅里叶变换美妙的部分，但对于某些信号处理应用来说，带状矩阵可以比傅里叶变换更加高效。
That s part of what makes Fourier wonderful. Nonetheless, for some signal-processing applications, banded matrices could prove more efficient than the Fourier transform.

对于一般的带状矩阵，详述对对称与非对称三对角化矩阵做QR分解后，Q矩阵与R矩阵的稀疏元素分布型态。
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.
在信号处理应用程序中，如果恢复信号需要乘上一个“满”的矩阵，那么带状矩阵提供的所有的速度优势都将不复存在。
In a signal-processing application, all the speed advantages offered by banded matrices would be lost if restoring the signal required multiplying it by a full matrix.
Strang的分析被应用于所谓的带状矩阵上；带状矩阵的绝大多数项都是0；唯一的例外是矩阵中心或靠近矩阵中心的对角带。
Strang s analysis applies to so-called banded matrices. Most of the Numbers in a banded matrix are zeroes; the only exceptions fall along diagonal bands, at or near the central diagonal of the matrix.
判断这些简单矩阵是否有带状逆阵要更容易，而如果它们有，那他们组合起来也会有。
It's easy to tell whether these simpler matrices have banded inverses, and if they do, their combination will, too.

带状是一种结构，但还有其他的，Brualdi希望数学家们把像Strang一样的方法用到其它结构类型的矩阵中去。
Bandedness is one type of structure, but there are others, and Brualdi expects other mathematicians to apply techniques like Strang s to other types of structured matrices.
