Computes the Eigenvalues of a square matrix.
EIGVAL(a)
a |
- |
A square matrix |
A single column series with as many rows as a. Each entry in the series is an Eigenvalue. The Eigenvalue in row n of EIGVAL corresponds to the Eigenvector in column n of EIGVEC.
x = {{1, 3, 4},
{5, 6, 7},
{8, 9, 12}}
eigval(x) == {19.964160, -1.473921, 0.509760}
x *^ eigvec(x) == eigvec(x) *^ diag(eigval(x)))
