WebA standard approach is to use a nonsingular matrix M, and rewrite the system as M−1Ax = M−1b. The preconditioner M needs to be chosen such that the matrix Aˆ = M−1A is better conditioned for the conjugate gradient method, or has better clustered eigenvalues for the GMRES method. 16.1 Preconditioned Conjugate Gradients WebCondition number reflects the sensitivity of "something" with respect to the change of data, in this case the perturbations of the matrix A.

The coeﬃcient matrix is called ill-conditioned because a small change in the constant coeﬃcients results in a large change in the solution. A condition number, deﬁned in more advanced courses, is used to measure the degree of ill-conditioning of a matrix (≈ 4004 for the above).

Note that this is before the effects of round-off error are taken into account; conditioning is a property of the matrix, not the algorithm or floating-point accuracy of the computer used to solve the corresponding system. In particular, one should think of the condition number as being (very roughly) the rate at which the solution x will … november 4th day

In linear algebra and numerical analysis, a preconditioner of a matrix is a matrix such that has a smaller condition number than . It is also common to call the preconditioner, rather than , since itself is rarely explicitly available. In modern preconditioning, the application of , i.e., multiplication of a column vector, or a block of column vectors, by , is commonly performed in a matrix-free fashion, i.e., where neither , nor (and often not even ) are explicitly available in a matrix form.
