In mathematics, a linear map (also called a linear transformation or linear operator) is a function between two vector spaces that preserves the operations of vector addition and scalar multiplication.
The term linear transformation is especially used for linear maps from a vector space to itself (endomorphisms).
In abstract algebra, a linear map is a homomorphism of vector spaces.
