Member of the polynomials class.

Syntax

[x, eig] = polyeig(a0, a1, ... , an)

Description

Solves the polynomial eigenvalue problem of degree n: (a0+lambda*a1+...+lambda^n*an)*x = 0. You can specify an unlimited number of input matrices. All matrices must be square and of the same size.

Examples

Inputs

Name	Description
a0	Specifies a real or complex square matrix.
a1	Specifies a real or complex square matrix of the same size as a0.
an	Specifies a real or complex square matrix of the same size as a0.

Outputs

Name	Description
x	Returns a matrix whose columns represent the eigenvectors of the input matrices.
eig	Returns the eigenvalues of the input matrices. eig is a vector.

Examples

A0 = [1, 2; 3, 4]
A1 = [2, 1; 1, 0]
A2 = [-1, -1; 0, 2]
[X, EIG] = polyeig(A0, A1, A2)
