Matrix norm - Wikipedia
Suppose a vector norm on and a vector norm on are given. Any matrix A induces a linear operator from to with respect to the standard basis, and one defines the corresponding induced norm or operator norm or subordinate norm on the space of all matrices as follows: where denotes the supremum. This norm measures how much the mapping induced by can stretch vectors. Depending on the vector norms , used, notation other than can be used for the operator norm.
