Why look into the last position?


Hi, everyone!
If the eigenvalues are ordered in decreasing order, isn’t the biggest eigenvalue in the first position? Why to look into the last position?

Yes, you are correct! We should look at the first positions of the vector to get the largest eigenvalues (because the order is decreasing).

Am I correct?

But from the printout, it is obvious that the eigenvalues are in increasing order, so the last value is the largest eigenvalue. Also, it is printing the forty-five largest eigenvalues, not ten.

so the “decreasing order” should be substituted by “ascending order” ?

Yes, I think so.

The following parameters influence the order of eigen values:

  1. which: str (defaults to “LM”)
  2. return_eigenvectors: bool (defaults to “true”)
