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: If the p-norm for vectors () is used for both spaces and , then the corresponding operator norm is: These induced norms are different from the "entry-wise" p-norms and the Schatten p-norms for … WebHence matrices are really vectors that are just written in a two-dimensional table-like manner.
