In general, the norms of any two vectors u and v in the same space satisfy the triangle inequality (2.5)||u||p+||v||p≥||u+v||p, for all p≥0. Though norms are defined for vectors, it is possible to extend them for matrices in different ways. For a matrix A (2.6)A≡[aij...

A scalar multiple to a norm is equal to the product of the absolute value of the scalar and the norm‖ka‖=|k|‖a‖. Norm of a vector obeys triangular inequality that the norm of a sum of two vectors is less than or equal to the sum of the norms ‖a+b‖⩽‖a‖+‖b‖.There...
In Linear Algebra, a norm is a way of expressing the total length of the vectors in a space. Commonly, the norm is referred to as the vector’s magnitude, and there are several ways to calculate the norm. How to Find the 𝓁1 Norm The 𝓁1 norm is the sum of the vector’s ...
Compared to most of feature extraction methods, the 2-D principal component analysis (2-DPCA) better preserves the structural information of images since it is unnecessary to transform the small size image matrices into high dimensional vectors during the calculation process. In order to improve the...
Usevecnormto treat a matrix or array as a collection of vectors and calculate the norm along a specified dimension. For example,vecnormcan calculate the norm of each column in a matrix. Extended Capabilities expand all C/C++ Code Generation ...
