WebMar 8, 2024 · Gershgorin’s Theorem provides a bound on where to find each eigenvalue, but it doesn’t provide an algorithm to actually calculate them. You can take an initial guess x 0 within each Gershgorin disk, and use the shifted inverse power method to find the eigenvalue closest to x 0.

The Gershgorin circle theorem is useful in solving matrix equations of the form Ax = b for x where b is a vector and A is a matrix with a large condition number. In this kind of problem, the error in the final result is usually of the same order of magnitude as the error in the initial data multiplied by the condition number of A. For instance, if b is known to six decimal places and the condition number of A is 1000 then we can only be confident that x is ac… swamp donkey oilfield services dawson creekWebJan 18, 2024 · $\begingroup$ Not sure if I get the issue, but Gershgorin's disc theorem says all eigenvalues must lie is in the union of the discs.
