Hi 定毅,
The command polyeig(A, 0, B) computes the eigenvalues of the matrix polynomial A - lambda*B evaluated at lambda=0. This is equivalent to computing the eigenvalues of the matrix A multiplied by the inverse of B.
The command polyeig(A, B) computes the eigenvalues of the matrix polynomial A - lambda*B.
The reason is that evaluating the matrix polynomial at different values of lambda can lead to very different results.
Thanks
