Thanks man ...... You are awesome Isaac ...... My issue is solved now ..... My workload is reduced to 1/20 and now I can find out 500 eigenvalues in just 5 mins .... which previously took me more than a day .........
I just need to do a small trick of commenting the list ee0 and run the code 500 times then I copy the complete output to the ee0 list in the code ....
Thanks again man .......
