If the function of interest is piece-wise linear, the extrema always occur at the corners. The norm of an uncertain matrix generally depends on the values of its uncertain elements. Norm type, specified as 2 (default), a different positive integer scalar, Inf, or -Inf.The valid values of p and what they return depend on whether the first input to norm is a matrix or vector, as shown in the table. norm:翻译为模或者内积,广义来说是一个函数 vector(向量) norms 1. eculidean(欧几里得)norm vector $x = (x_1;x_2; ; x_n)$ 其ec Dann gilt für die entsprechenden Matrixnormen: BA ≤B A.

In Section 4 we show this for general measures of discrepancy, generalizing previous results [3,4] for binary target matrices. 1.1 Matrix Norm problem: setting and motivation 1.1.1 Matrix Norm problem. In the Thesis, we focus on the Matrix Norm problem as follows: Let E, H be flnite-dimensional real vector spaces equipped with norms k¢kE, k¢kH, respectively, and let L(E;H) be the space of linear mappings from E to H; from the Matrix norm the maximum gain max x6=0 kAxk kxk is called the matrix norm or spectral norm of A and is denoted kAk max x6=0 kAxk2 kxk2 = max x6=0 xTATAx kxk2 = λmax(ATA) so we have kAk = p λmax(ATA) similarly the minimum gain is given by min x6=0 kAxk/kxk = q λmin(ATA) Symmetric matrices, quadratic forms, matrix norm, and SVD 15–20 In Matrix: Sparse and Dense Matrix Classes and Methods.

Computes a matrix norm of x, using Lapack for dense matrices.The norm can be the one ("O", or "1") norm, the infinity ("I") norm, the Frobenius ("F") norm, the maximum modulus ("M") among elements of a matrix, or the spectral norm or 2-norm ("2"), as Matrix 1-norm or maximum column-sum of the input, returned as a scalar.

Since n × n matrices can be multiplied, the idea behind matrix norms is that they should behave “well” with re-spect to matrix multiplication. We define a matrix norm in terms of a given vector norm; in our work, we use only the p-vector norm, denoted as r X p.
