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...

Now, in this section we’re going to be looking at a special kind of transformation called a linear transformation. Here is the definition of a linear transformation.

Nov 3, 2009 A linear transformation is an important concept in mathematics because many real world phenomena can be approximated by linear models.

is called the matrix of the linear transformation with respect to the basis (e1, e2, e3). The columns of this matrix are the coordinates of (u1, u2, u3).

Since each linear transformation of the plane has a unique standard matrix, we will identify linear transformations of the plane by their standard matrices. It can be shown that if $A$ is invertible, then the linear transformation defined by $A$ maps parollelograms to parallelograms.

null space of a linear transformation: The null space of a linear transformation T is the set of vectors v in its domain such that T(v) = 0. nullity of a linear transformation: The nullity of a linear transformation is the dimension of its null space.
