Rutishauser method and Gerschgorin circles method to compute eigenvalues of arbitrary matrices
T. D. Roopamala · IOSR Journal of Engineering · 2012
In this paper a graphical technique using Gerschgorin circles to computed eigenvalues of a system matrix is presented.The results have been compared with the existing method.A suitable step length has been taken at the Gerschgorin bound and in this step length the Bisection method is applied to compute the eigenvalues of the system matrix.
