Eigenvectors Routine in Third Edition?

Hi, folks.

First post in this forum. I just came across it recently; I wish I had known about it sooner.

I have an old edition of Numerical Recipes (I purchased it in 1987, and the publication date is 1987). It is still on my bookshelf and is well-used. I don't have the Third Edition, but one routine I miss in my old edition is a routine for calculating the eigenvectors as well as the eigenvalues of a real, general matrix. The old edition has a routine for computing the eigenvalues only of a real, general matrix (no eigenvectors). The absence of such a routine is the main reason I later discovered the EISPACK routines and the NETLIB site. Does the Third Edition include a routine that computes the eigenvectors of a real, general matrix?

Yes.
