Thanks to all for useful comments. I have followed the eigenvalue calculation codes from "mastering algorithms with perl" book. I hope that is outdated. I will look at some updated tutorials for eigenvalue calculation, i appreciate if some one can post updated tutorials link. I formulated my own algorithm for eigenvalue calculation, PCA analysis. and later I came to know about this PDL package when I got struck with setting up algorithm for eigenvector calculation, thanks to the developers, it will save my time. I am working with 3 by 3 symmteric matrix, as the matrix is simple, i calculated the eigenvalues without much trouble.
