Question: Eigenvector ordering

Question:Eigenvector ordering

Hi all,

Is there a way to call Eigenvectors(), order the returned eigenvalues from largest to smallest, and have the returned eigenvectors reflect this ordering? I've tried a sort() on the eigenvalues which orders them successfully, but I can't seem to figure out how to apply the ordering changes to my eigenvectors.

I tried to take the 'brute force' approach and calculate the eigenvalues, use them in the characteristic matrix and after row reducing use BackwardSubstitute, but this leaves me with parameters (like _t21) that I don't know how to define (help with that would be much appreciated too :P)

Thanks for reading & thanks in advance for any help!
