Hi, I am using Eigenvalues[S] to find the eigenvalues of a matrix. When S is a non singular matrix(size 500X500), the result comes very fast and I get numerical values of the eigenvalues. When S is singular, or very close to singular, the same command takes a very long time and I get the solution in the following form: ------------------------------------------ (Root[1 - 685943599676205704518784329322181239368381737604683300823488051563928004 00 #1 + 422683709458129987020719509512322527334828765466847787730553472756576 3506258708383447822509137758993927488132783442108014806593541358448555767500 #1^2 - 4756334945955210795836139142803033950863408883091629073980127621488009 953862277690213957742565926625592512302479312067202413373431157721376895723657 92383917222956224461254901373715676847804396794660504978304000000 #1^3 + 149043931613976872173805300357234123824177187156376686486092172926647734083521 317893308585359969916780878974219953919649726995574191854952913882459023542023 1375808689867514677371127 .......... ------------------------------------------------------------- How can I get the solution(eigenvalues) as numerical values? Thank you, Amit
