Deflated matrix
WebDeflation is a well-known technique to accelerate Krylov subspace methods for solving linear systems of equations. In contrast to preconditioning, in deflation methods singular systems have to be solved. The original system is multiplied by a projection which leads to a singular linear system which can be more favorable for a Krylov subspace method. Deflation … Web(1) This question deals with deflation of eigenvalues/vectors from matrices. You are given the matrix 309 228 -240 A= 60 -117 510/49, 12 6 298 and are told that the vector v = (-8 10 9)' is an eigenvector of A (which you are surely able to check!) (i) Deflate v from A. (ii) Find (say, directly) the eigenvectors of the 2X2 deflated matrix.
