矩阵单位

In this paper, we mainly use complex semisimple algebras knowledge. First, we give the structure formula of C. Second, we show that any n x n symmetric matrix A is congruent under the symplectic group to the direct sum of a identity matrix and a tridiagonal matrix.

记正交代数和辛代数的交集构成的李代数为L，本文主要是运用复半单李代数的知识，首先给出了L的结构公式，然后给出了任一n×n对称矩阵A辛合同于一个单位矩阵和一个三对角矩阵的直和。

By using the secondary unit matrix, the inverse problem of secondary eigenvalue of anti-skew-symmetric is solved.

本文在对问题的理论推导中，充分利用了次单位矩阵的作用，提供了将次反对称矩阵的逆次特征值问题转为反对称矩阵的逆特征值问题来解决的新思路。

To overcome the difficulty caused by the fact that the Lax pair depends on thesolution of the equation as |k|→∞,we write the Darboux matrix with N-poles inthe form:〓,where factor 〓 is a gauge transformation which isindepent from k and 〓 tends to the unit-matrix I as |k|→∞.

为了克服当|k|→∞时，Lax对仍依赖于方程的解所引起的困难，我们把含N对极点的Darboux矩阵〓分解为两部分：〓，其中〓为与参数k无关的2×2矩阵，它相当于一个规范变换。而〓当|k|→∞时趋于单位矩阵I。

When a matrix causes no transformations, you have what is known as a unit or identity matrix.

当一个矩阵的作用没有产生型变时，我们把这个矩阵叫做单位矩阵

We then load the identity matrix in the stack (which simply resets the current matrix to the identity matrix) and then we specify that we would like an orthographic projection of the objects on the viewport.

我们然后加载堆栈中的矩阵（它只是重置当前矩阵为单位矩阵），然后我们指定我们想一对视的对象正投影。

The data symbols may be sent on orthogonal spatial channels with the eigenmode matrix, on different spatial channels with the steering matrix, or from different transmit antennas with the identity matrix.

数据符号可以用本征矩阵在正交空间信道上进行发射，用导引矩阵在不同的空间信道上进行发射，或用单位矩阵从不同的发射天线进行发射。

Any square matrix (a matrix is square if its number of rows equals its number of columns) is an identity matrix if all values are 0 except those diagonal from the top left to the bottom right which instead have the value of 1 - the locations where the row position equals the column position.

任何方形矩阵(一个矩阵的行，列数相同)，只要是从左上角到右下角这条对角线上的元素值为1，其余为0的，就是一个单位矩阵。

A transmitting entity performs spatial processing on data symbols for each subband with an eigenmode matrix, a steering matrix, or an identity matrix to obtain spatially processed symbols for the subband.

发射实体用本征矩阵、导引矩阵或单位矩阵对每个频率子带的数据符号进行空间处理，以获得该子带的空间处理符号。

The characteristic vector of the real symmetric matrix should be found out, which is orthogonalized and normalized to a standard orthogonal base and is used as row vector to construct the transformation matrix P, so the P~(-1)AP can be made into diagonal matrix.

实对称矩阵A经相似变换P-1AP可化为对角矩阵，在x =Py 下，不一定能化A的二次型为标准型；应寻求对称矩阵A的特征向量，将其正交化并单位化作为标准正交基，作为列向量构造变换矩阵P，可使P-1AP=Λ为对角阵，在x =Py 下，要将二次型化为标准型，且二次项系数即为对角阵Λ主对角线上元素。

Although I won't discuss the math behind matrix concatenations, suffice it to say it's important to have an understanding of the term because you will likely encounter it when working in the world of matrices.

我不解释矩阵连接的数学含义，但是请记住这是很重要的术语，以为你要和矩阵打交道就难免要用到它（翻译的人猜，'它'指的是单位矩阵而不是矩阵连接--b

As she looked at Warrington's manly face, and dark, melancholy eyes, she had settled in her mind that he must have been the victim of an unhappy attachment.

每逢看到沃林顿那刚毅的脸，那乌黑、忧郁的眼睛，她便会相信，他一定作过不幸的爱情的受害者。

Maybe they'll disappear into a pothole.

也许他们将在壶穴里消失
