These norms treat an matrix as a vector of size , and use one of the familiar vector norms. For example, using the p-norm for vectors, p ≥ 1, we get: This is a different norm from the induced p-norm (see above) and the Schatten p-norm (see below), but the notation is the same. The special case p = 2 is the Frobenius norm, and p = ∞ yields the maximum norm. Webi.e., when the matrix is almost not invertible, i.e., almost singular. A classic example of an ill conditioned matrix is the Hilbert matrix which we have already encountered Here are …

WebJul 17, 2024 · A condition number for a matrix and computational task measures how sensitive the answer is to perturbations in the input data and to roundoff errors made during the solution process. When we simply say a matrix is "ill-conditioned", we are usually just thinking of the sensitivity of its inverse and not of all the other condition numbers. Norms fnf stylish
