1) for all positive integers r , where ρ (A) is the spectral radius of A . For symmetric or hermitian A , we have equality in (1) for the 2-norm, since in this case the 2-norm is precisely the spectral radius of A . For an arbitrary matrix, we may not have equality for any norm; a counterexample would be A = [0 1 0 0] , … Ver mais In mathematics, a matrix norm is a vector norm in a vector space whose elements (vectors) are matrices (of given dimensions). Ver mais 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 … Ver mais 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 Ver mais 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 Ver mais Suppose a vector norm $${\displaystyle \ \cdot \ _{\alpha }}$$ on $${\displaystyle K^{n}}$$ and a vector norm $${\displaystyle \ \cdot \ _{\beta }}$$ Ver mais 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 Ver mais Another source of inspiration for matrix norms arises from considering a matrix as the adjacency matrix of a weighted, directed graph.
