# What is Linear Transformations? Linear transformations are a function $T(x)$, where we get some input and transform that input by some definition of a rule. An example is $T(\vec{v})=A \vec{v}$, where for every vector coordinate in our vector $\vec{v}$, we have to multiply that by the matrix A.

A linear transformation is also known as a linear operator or map. The range of the transformation may be the same as the domain, and when that happens, the transformation is known as an endomorphism or, if invertible, an automorphism.

Thus, the matrix form is a very convenient way of representing linear functions. In addition to multiplying a transform matrix by a vector, matrices can be … Matrix representation of a linear transformation: Let V and W be an n and m dimensional vector spaces over the field of real numbers, R.Also, let B V = {x 1, x 2, …, x n} and B W = {y 1, y 2, …, y m} be ordered bases of V and W, respectively.Further, let T be a linear transformation from V into W.So, Tx i, 1 ≤ i ≤ n, is an element of W and hence is a linear combination of its basis Matrix representation of a linear transformation: Let V and W be an n and m dimensional vector spaces over the field of real numbers, R.Also, let B V = {x 1, x 2, …, x n} and B W = {y 1, y 2, …, y m} be ordered bases of V and W, respectively.Further, let T be a linear transformation from V into W.So, Tx i, 1 ≤ i ≤ n, is an element of W and hence is a linear combination of its basis A linear transformation (multiplication by a 2×2 matrix) followed by a translation (addition of a 1×2 matrix) is called an affine transformation. An alternative to storing an affine transformation in a pair of matrices (one for the linear part and one for the translation) is to store the entire transformation in a 3×3 matrix. The two defining conditions in the definition of a linear transformation should “feel linear,” whatever that means. Conversely, these two conditions could be taken as exactly what it means to be linear. As every vector space property derives from vector addition and scalar multiplication, so too, every property of a linear transformation derives from these two defining properties.

So, we can talk without ambiguity of the matrix associated with a linear transformation $\vc{T}(\vc{x})$. Thus, multiplying any matrix by a vector is equivalent to performing a linear transformation on that vector.

## that every linear transformation between finite-dimensional vector spaces has a unique matrix A. BC with respect to the ordered bases B and C chosen for the

In this article, we will see how the two are related. We assume that all vector spacesare finite dimensional and all vectors are written as column vectors.

### Let's take the function f(x,y)=(2x+y,y,x−3y), which is a linear transformation from R2 to R3. The matrix A associated with f will be a

The matrix composed by the vectors of V as columns is always invertible; due to V is a basis for the input vector space.

The Ker(L) is the same as the null space of the matrix A.We have The matrix composed by the vectors of V as columns is always invertible; due to V is a basis for the input vector space. This practical way to find the linear transformation is a direct consequence of the procedure for finding the matrix of a linear transformation.
