Vector and matrix norms Syntax n = norm(v) n = norm(v,p) n = norm(X) n = norm(X,p) n = norm(X,'fro') Description n = norm(v)返回向量v的欧几里德范数。该范数也称为2范数,向量幅度或欧几里德...
Matrix and vector norms.Steven E. Pav
In this discussion, we’ll first look at vector norms. We’ll get to matrix norms later. Mathematically, a norm is a function (or a mapping) from an n-dimensional vector space to the set of real numbers: Note: Norms are also defined on complex vector spacesC^n → Ris a valid defini...
Chapter 7 – Vector and Matrix NormsThis chapter begins the study of numerical linear algebra. The length, or norm, of a vector is defined, and the 2-, 1-, and infinity vector norms are defined. There are inequalities that bound each norm in terms of the others. The chapter ...
范数,是具有“长度”概念的函数。 5.1 向量范数 其中2-范数就是通常意义下的距离。 5.2 矩阵范数 矩阵范数反映了线性映射把一个向量映射为另一个向量,向量的“长度”缩放的比例。 范数理论是矩阵分析的基础,度量向量之间的距离、求极限等都会用到范数,范数还在机器学习、模式识别领域有着广泛的应用。
THIS paper examines the conditions under which a matrix norm is matched with only one vector norm. Applications of the results will be described in a subsequent paper.doi:10.1016/0041-5553(69)90149-9Kh.D. IkramovN.V. PetriElsevier B.V.Ussr Computational Mathematics & Mathematical Physics...
