Hi,
'eigenvectors' failed to work on numeric 2x2 matrix below..
m: matrix( [10.48273938962865,14.15187882832064],
[21.22781824248096,31.71055763210962] );
eigenvectors(m)
It gave the following error message..
algsys failure: the eigenvector(s) for the 1 th eigenvalue will be missing.
algsys failure: the eigenvector(s) for the 2 th eigenvalue will be missing.
and just returned the eigenvalues..
[0.77255984019432, 41.42073711336268]
Using another software.. the eigenvectors should be..
eigenvector of eigenvalue 0.7725598869933528:
(-0.8245648401323937, 0.5657674649689922)
eigenvector of eigenvalue 41.42073713474491:
(0.4159735579192842, 0.9093767091321241)
Anyone knows what has happened?
I noticed little difference in eigenvalues after 7-8th decimal place
between Maxima and that another software.. maybe this caused the
failure?
Best regards,
