Eigen vector and eigen value

2016-01-11 11:58 465 查看
对于NxN矩阵A,至少存在N个向量,矩阵A仅仅对向量进行缩放,这些特殊的向量就是eigen
vectors。

For a matrix A of dimension NxN, there are at least N vectors that are only shrunken or stretched by A. In this area, eigen means special, and this special vectors are called eigen vectors e1 ...eN.

A e1= lambda1 e1;  e1 called eigen vectors;lambda called eigen values.
