WebFeb 2, 2024 · The condition number of a diagonal matrix D is the ratio between the largest and smallest elements on its diagonal, i.e., cond(D) = max(D ii) / min(D ii).It's important to note that this is only true when using the matrix 2-norm for computing cond(D). This is largely because D's diagonal elements are its eigenvalues.
Webx = 1,y = 1. 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). WebDefine the matrix L∈ Cm×p such that its j-th column is Bju. Let A∈ Cm×n be the matrix we want to probe and suppose Alies in the span of B. Say A= Xp i=1 ... Conditioning of L.
