Let $V$ and $W$ be vector spaces over $\mathbb{F}$. A transformation $A:V\to W$ is a linear transformation if
- $A(x+y)=Ax+Ay$ for $x, y \in\mathbb{F}^n$
- $A(cx)=cA(x)$ for $c\in\mathbb{F},x\in\mathbb{F}^n$
Concepts
A shorter check for linear transformation is $T(\alpha_1 x_1+\alpha_2 x_x)=\alpha_1 T x_1+\alpha_2 T x_2$.Let $A\inM_{m, n}(\mathbb{F})$ be a transformation $A:\mathbb{F}^n\to\mathbb{F}^m$, where $A=[a_{ij}]$ and $x=\begin{bmatrix}x_1 \\ \vdots \\ x_n\end{bmatrix}\in \mathbb{F}^n$ and $[x]_j=x_j$. Then $$\begin{align*} Ax:=\begin{bmatrix}a_{11}x_1+\dots + a_{1n}x_n \\ \vdots \\ a_{n1}x_1 + \dots + a_{mn}x_n\end{bmatrix} \end{align*}$$ Every linear transformation can be represented as a matrix.
