specific order of eigenvalues

Hello,

I have the following problem:

I calculated the eigenvalues of an (nxn)-Matrix with [V,D] = eig(A,'vector') and got physical correct results. But I have problem with the order of the eigenvalues. The Matrix elements are calculated via

<\psi_i|\hat{A}|\psi_j>

and the order of the Eigenvalue vector has to fit to the order of the eigenvector |\psi> For example: I got Eigenvalues of D = [-2,-1,-1,0,0,1,1,2,] but need to get something like that D = [-1,0,1,...] Is it possible to keep the order condition or to gain it from somewhere? Maybe by another another possibility than eig() or eigs()?

Kind regards and thanks for your help,

rene

Hm, is there no solution or is the kind of ask not clear enough? I can give more details - just ask what you need to know to help...

You should test whether some friend of yours can understand your question if he/she does not know about your problem.

E.g. what is \psi_i|\hat{A}|\psi_j ?

What has D = [-2,-1,-1,0,0,1,1,2,] to do with D = [-1,0,1,...] ?

Best wishes

Torsten.
