Outputs: EVL() - a 0-based (n-size) array containing the eigenvalues EVC() - a 0 based (n x n - sized ) array. Each column k of the array should represent an eigenvector that corresponds to k eigenvalue of the EVL() array ErrorVaue - Contains Error Codes if operation not succesful Deliverables: Just this procedure with comments for every step and an explanation for the method that has been used.

They are simple and straight forward. I'd be glad to do this task for you. I've over 6 years experience programming in VB++. My specialization is mathematical tasks. I've already done computation of eigenvalues and eigenvectors. So, it wouldn't cost you much. It will be finished in a few hours. I will deliver well commented code and help understand it if necessary. Good luck. Sincerely, Alex.           See 3 private reply(ies) to/from Alex K.
