In the case of a 3x3 matrix, there will be three eigenvalues, counted with multiplicity, since the characteristic equation is a cubic polynomial. Substituting these known eigenvalues into the eigenvector equation and solving for the unknown vector v will yield the corresponding eigenvectors. How ...
On the previous page, Eigenvalues and eigenvectors - physical meaning and geometric interpretation applet we saw the example of an elastic membrane being stretched, and how this was represented by a matrix multiplication, and in special cases equivalently by a scalar multiplication....
This calculator allows you to enter any square matrix from 2x2, 3x3, 4x4 all the way up to 9x9 size. It will find the eigenvalues of that matrix, and also outputs the corresponding eigenvectors.For background on these concepts, see 7. Eigenvalues and Eigenvectors ...
Eigenvalues of a Matrix & The Characteristic Equation from Chapter 6/ Lesson 2 44K Understand eigenvalues and eigenvectors of a matrix. Compute eigenvalues using the characteristic equation. Practice finding eigenvalues for 2x2 and 3x3 matrices. ...
The eigenvalues of a matrix are the scalars by which eigenvectors change when some transformation is applied to them. Learn how to find the eigenvalues of 2x2 and 3x3 matrices using the characteristic equation with examples.

However it is possible to get a change of basis in which matrix A takes a simpler form called Jordan form. In both cases, Jordan and diagonal forms we need to calculate eigenvalues and eigenvectors of A. Extended Therory Consider the linear map (also called endomorphism) given by: F...
数学上,线性变换的特征向量(本征向量)是一个非退化的向量,其方向在该变换下不变。该向量在此变换下缩放的比例称为其特征值(本征值)。一个线性变换通常可以由其特征值和特征向量完全描述。特征空间是相同特征值的特征向量的集合。“特征”一词来自德语的eigen。1904年希尔伯特首先在这个意义下使用了这个词,更早亥尔...
