Linear transformation as matrix multiplication

Expresses a linear transformation T acting on a vector x as multiplication by a fixed matrix A. It is used to represent linear maps concretely so they can be computed and analysed with matrix methods.

T(\vec{x}) = \mathbf{A}\vec{x}

What the symbols mean

the linear transformation (mapping from one vector space to another)
input vector
transformation matrix representing T in the chosen bases
