WebMathematica is quite capable of computing the eigenvalues of matrix pencils (i.e., the generalized eigenproblem). Eigenvalues [] / Eigenvectors [] / Eigensystem [], as well as CharacteristicPolynomial [] and SchurDecomposition [], are all able to handle matrix pencils, as long as the matrix contains inexact elements. For instance: WebOct 24, 2012 · while Mathematica yields: EigVec = 0.2833 -1.2833 1 0.6417 -0.1417 -2 1 1 1 From the Matlab documentation: "For eig (A), the eigenvectors are scaled so that the norm of each is 1.0.". Mathematica on the other hand is clearly scaling the eigenvectors so that so the final element is unity.

WebMar 24, 2024 · Eigenvalues are a special set of scalars associated with a linear system of equations (i.e., a matrix equation ) that are sometimes also known as characteristic roots, characteristic values (Hoffman and Kunze 1971), proper values, or latent roots (Marcus and Minc 1988, p. 144). WebIn Mathematica, vector p -norms can be computed with the function Norm. The 1-, 2-, and -norms are demonstrated in the following examples: In [3]:= In [4]:= Out [4]= In [5]:= Out [5]= In [6]:= Out [6]= The 2-norm is particularly useful and this is the default: In [7]:= Out [7]= Norms are implemented for vectors with exact numerical entries: WebEigenvectors with numeric eigenvalues are sorted in order of decreasing absolute value of their eigenvalues.
