Question

I have

k=linalg.eig(Ki)

where Ki for example is :

[[ 1.84026465 -0.463138  ]
 [-0.463138    3.83931947]]

and result k is:

(array([ 1.73817877,  3.94140535]), array([[-0.97655787,  0.21525501],
       [-0.21525501, -0.97655787]]))

how can I display just biggest value from k (I don’t know why are there 2 array, if I calculate by hand only first array is result..) ? I’m looking something like max(k)…anyone know?

Answer 1

linalg.eig returns two arrays, first the eigenvalues, then the eigenvectors.

If you want the maximimum eigenvalue, then

vals,vecs=linalg.eig(Ki)
max_eigenvalue = vals.max()
