Sig sauer p226 navy for saleI wanted to make sure I understand how to find the matrix for a linear transformation, but for a non-standard basis. Lets say for example you have the linear operator in $\mathbb{F}^2$ defined in the standard coordinates by T$\begin{pmatrix}x\\y\end{pmatrix}$ = $\begin{pmatrix}x+y\\y-x\end{pmatrix}$ for the basis $(2,3)^T$, and $(1,2)^T$.
A matrix representation of the linear transformation relative to a basis of eigenvectors will be a diagonal matrix — an especially nice representation! Though we did not know it at the time, the diagonalizations of Section SD were really about finding especially pleasing matrix representations of linear transformations. Here are some examples.

For any linear transformation T between R n and R m, for some m and n, you can find a matrix which implements the mapping. This means that multiplying a vector in the domain of T by A will give the same result as applying the rule for T directly to the entries of the vector.A basic approach for finding a representation of the transfer matrix as ratios of polynomials, where the polynomials are given in a standard representation, is as follows. In general each sample of the input data yields a matrix of ratios of polynomials, where all polynomials have a low degree.
