WebOct 21, 2013 · Matrix or vector norm. This function is able to return one of seven different matrix norms, or one of an infinite number of vector norms (described below), depending on the value of the ord parameter. Notes For values of ord <= 0, the result is, strictly speaking, not a mathematical ‘norm’, but it may still be useful for various numerical purposes. In mathematics, a matrix norm is a vector norm in a vector space whose elements (vectors) are matrices (of given dimensions). Preliminaries [ edit] Given a field of either real or complex numbers, let be the K - vector space of matrices with rows and columns and entries in the field . A matrix norm is a norm on . See more In mathematics, a matrix norm is a vector norm in a vector space whose elements (vectors) are matrices (of given dimensions). See more These norms treat an $${\displaystyle m\times n}$$ matrix as a vector of size $${\displaystyle m\cdot n}$$, and use one of the familiar vector norms. For example, using the p-norm for … See more A matrix norm $${\displaystyle \ \cdot \ }$$ is called monotone if it is monotonic with respect to the Loewner order. Thus, a matrix norm is increasing if See more For any two matrix norms $${\displaystyle \ \cdot \ _{\alpha }}$$ and $${\displaystyle \ \cdot \ _{\beta }}$$, we have that: $${\displaystyle r\ A\ _{\alpha }\leq \ A\ _{\beta }\leq s\ A\ _{\alpha }}$$ for some positive numbers r and s, for all matrices See more Suppose a vector norm $${\displaystyle \ \cdot \ _{\alpha }}$$ on $${\displaystyle K^{n}}$$ and a vector norm $${\displaystyle \ \cdot \ _{\beta }}$$ on $${\displaystyle K^{m}}$$ are … See more The Schatten p-norms arise when applying the p-norm to the vector of singular values of a matrix. If the singular values of the $${\displaystyle m\times n}$$ matrix $${\displaystyle A}$$ are denoted by σi, then the Schatten p-norm is defined by See more Another source of inspiration for matrix norms arises from considering a matrix as the adjacency matrix of a weighted, directed graph.
