Yes, Dear Luis, your are fast and right !
just confirm that using meigen() to obtain eigenvectors (right) if you
perform matrix
multiplication (x) the vector are in the rows but if you want to see they
you need the
transpose
Thanks !

Dear Guillermo,
I guess the eigenvectors are the rows, not the columns, and they are
normalized!

Dear PDL developers,
Trying to use meigen() for eigenvalue problem with matrix 4x4 without
threading for now, I realize that eigenvalues
Dear PDL developers,
Trying to use meigen() for eigenvalue problem with matrix 4x4 without
threading for now, I realize that eigenvalues seems did not have any
ordered output, is not it?
In the first example below the second eigenvalue is larger than the first
