Thanks John. Those are the steps I followed, and to no avail. Interestingly, I downloaded and installed SciPy, and ran the same eigenvector problem. SciPy greatly speeds up the calculation...was 1.5 hours using Numeric, now only 15 min with SciPy.
Unfortunately, SciPy only solves ordinary and generalized eigenvalue problems of a square matrix. They do not test to see if the matrix is symmetric, then call the appropriate routine from LAPACK. Daran -- http://mail.python.org/mailman/listinfo/python-list
