WebMar 5, 2024 · For a linear transformation L: V → V, then λ is an eigenvalue of L with eigenvector v ≠ 0 V if. (12.2.1) L v = λ v. This equation says that the direction of v is invariant (unchanged) under L. Let's try to understand this equation better in terms of matrices. Let V be a finite-dimensional vector space and let L: V → V. WebIn linear algebra, the eigenvectors of a square matrix are non-zero vectors which when multiplied by the square matrix would result in just the scalar multiple of the vectors. i.e., a vector v is said to be an eigenvector of a square matrix A if and only if Av = λv, for some scalar λ.Here, v is an eigenvector as when it multiplied by A resulted in λv, which is a …

WebJun 18, 2015 · I'm using Eigenvectors to get the eigenvectors for some matrixes, but the eigenvectors seems to have some phase jump. Here is an example: Say we have a 2 by 2 matrix { {2., Exp [I x]}, {Exp [-I x], 2.}} and x is a number. Now if we change x smoothly in some region, we would expect the eigenvector or eigenvalues changes smoothly.
