WebNov 19, 2014 · [V,D] = eig (A) returns matrix V, whose columns are the right eigenvectors of A such that A*V = V*D. The eigenvectors in V are normalized so that the 2-norm of each is 1. [V,D] = eig (A,'nobalance') also returns matrix V. However, the 2-norm of each eigenvector is not necessarily 1. WebNov 19, 2024 · I used MATLAB eig function to check answer, the answer should be 3.3876 for largest eigenvalue and [-0.371748 0.601501 -0.601501 0.371748] for the corresponding eigenvector. I have no idea why it is wrong. WebMatLab function eig (X) sorts eigenvalues in the acsending order, so you need to take the last two colmns of matrix V Also do remember that if you try to perform factor analysis you can simply use MatLab's princomp function or center the data before using eig. overwraps.com

If you did that in MATLAB or Numpy, there'd be a big performance penalty. – enobayram Jul 1, 2013 at 16:01 Add a comment 3 Answers Sorted by: 8

WebEigenvalue Problems A real number 2 such that the BVP (5) has a non-trivial solution y (x) is called an eigenvalue of the BVP and the function y (x) is called an eigen-function associated to (or corresponding to) 2 n. It turns out that if y (x) is an eigenfunction, then so is any non-zero multiple Cy (x), so we usually just take the constant C= 1.

WebScilab eigenvector matrix can differ from Matlab one. eig (A,'nobalance') There is no Scilab equivalent for "nobalance" option. See examples. eig (A,B,flag) There is no Scilab equivalent for flag.
