... For a vector, the “norm” means the same thing as the length (geometrically, not the number of entries). Another way to think of it is how far the vector is from being the zero vector. We want to measure a matrix in much the same way and the norm is such a quantity. The usual definition of the norm o ...

Linear Algebra and Matrices
... If A is invertible and maps U into V, both n dimensional, then we define A−1 , which maps V into U, by the equation A−1 (y0 ) = x0 where y0 is in V and x0 is in U and satisfies Ax0 = y0 (such an x0 exists by (2) and is unique by (1)). Thus defined A−1 is a legitimate transformation from V to U. That ...
