WebEigenvalues and Eigenvectors. Linear Algebra. Illustrates how the Gershgorin circle theorem can be used to bound the eigenvalues of a matrix. You can select a random 4 × … 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… WebMar 24, 2024 · If, in the Gershgorin circle theorem for a given , for all , then exactly one eigenvalue of lies in the disk.
