Does there exist a matrix A for which A M = M T for every M. The answer to this is obviously no as I can vary the dimension of M. But now this lead me to think , if I take , lets say only 2 × 2 matrix into consideration. Now for a matrix M, A = M T M 1 so A is not fixed and depends on M, but the operation follows all conditions of a linear transformation and I had read that any linear transformation can be represented as a matrix. So is the last statement wrong or my argument flawed?

How do we know that S must be induced by some matrix B?
Functions T:RnRm are called transformations from Rn to Rm
A transformation T:RnRn has an inverse if there is some transformation S such that TS=ST=1Rn
Let T=TA:RnRn denote the matrix transformation induced by the n×n matrix A, that is T(x)=Ax
We have:
BAx=S[T(x)]=(ST)x=1Rn(x)=x=Inx

Consider K n , K m , both with the | | . | | 1 -norm, where K = R or C .
Let | | T | | = i n f { M 0 : | | T ( x ) | | M | | x | |   x K n } be the operator norm of a linear transformation T : K n K m .
Show that the operator norm of the linear transformation T is also given by:
| | T | | = m a x { i = 1 m | a i j | , 1 j n } =: | | A | | 1
where A is the transformation matrix of T and a i j it's entry in the i-th row and j-the column.
