eigenvectors和eigenvalues的求解逻辑如下：特征向量： 定义：特征向量是在矩阵的线性变换下，方向保持不变，仅长度发生缩放的特殊向量。 求解逻辑：通过寻找在矩阵变换下“不动”或仅按固定比例“移动”的向量。这可以通过解矩阵方程来实现。特征值： 定义：特征值是特征向量在矩阵变换下长度的缩放比例。 求...

在理解线性代数的核心概念中，eigenvectors（特征向量）和eigenvalues（特征值）起着关键作用。让我们通过直观的图形方式探索它们的求解逻辑。想象一个矩阵，它是线性变换的数学描述，当我们对它进行作用时，它会改变向量的方向，但保持其长度的某种比例。这时，如果存在一个特殊的向量，即特征向量，它不仅在变...
矩阵分析讲义 Eigenvalues and eigenvectors
This paper highlights this struggle by considering some conceptual processes and difficulties students find in learning about eigenvalues and eigenvectors. We use the theoretical framework of Tall's three worlds of mathematical thinking, along with perspectives from Dubinsky's APOS (action, process, ...
MATLAB provides built-in functions to compute eigenvalues and eigenvectors. Using eig This function computes the eigenvalues and eigenvectors of a matrix. Syntax e=eig(A)[V,D]=eig(A)[V,D,W]=eig(A)e=eig(A,B)[V,D]=eig(A,B)[V,D,W]=eig(A,B)[___]=eig(A,balanceOption)[___]...

Eigenvalues and eigenvectors refer to the axes directions within a covariance matrix that capture the most significant variance, known as principal components. Eigenvalues are coefficients attached to eigenvectors, indicating the amount of variance present in each principal component. ...
