The meaning of NORM is an authoritative standard : model. How to use norm in a sentence. Synonym Discussion of Norm.
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...

An inner product norm on the vector space of all (n+k)-linear functions on Em is defined. The tensor and symmetric products of A and B are denoted, respectively, by A⊗B and AċB.lt is shown that and that this result is best possible.J.W. Neuberger...
It requires only matrix-vector products at each iteration, but does not require the explicit access to matrix. Huggins and Zucker [33] proposed greedy basis pursuit to accelerate basis pursuit by building up sparse representation sequentially as matching pursuit does. This algorithm is based on ...

A first example of matrix norm is the Frobenius norm (2.47)‖A__‖F:=∑i,j=1n[A__]ij2=A__A__T. It can be checked that ‖⋅‖F is compatible with the Euclidean vector norm ‖⋅‖2. The Frobenius norm will be useful in Part 3 when deriving the energy balance for continuum...
