# What is the domain of a transformation?

## What is the domain of a transformation?

The domain of a linear transformation is the vector space on which the transformation acts. Thus, if T(v) = w, then v is a vector in the domain and w is a vector in the range, which in turn is contained in the codomain.

## What is range of Matrix?

In linear algebra, the column space (also called the range or image) of a matrix A is the span (set of all possible linear combinations) of its column vectors. The column space of a matrix is the image or range of the corresponding matrix transformation. Let be a field.

## How do you find the basis of a range?

To find a basis for the range of T, remember that the columns of M span its range . Find the largest INDEPENDENT subset of the set of the columns of M . To find a basis for the range of T, remember that the columns of M span its range . Find the largest INDEPENDENT subset of the set of the columns of M .

## Is null space a subspace?

The null space of an m×n matrix A is a subspace of Rn. Equivalently, the set of all solutions to a system Ax = 0 of m homogeneous linear equations in n unknowns is a subspace of Rn.

## What vector space is NUL A a subspace of?

The null space of an m × n matrix A is a subspace of Rn. Equivalently, the set of all solutions to a system Ax = 0 of m homogeneous linear equations in n unknowns is a subspace of Rn. Proof: Nul A is a subset of Rn since A has n columns.

## Is column space a subspace?

The space spanned by the columns of A is called the column space of A, denoted CS(A); it is a subspace of R m . even if m ≠ n.

## Does row space equals column space?

TRUE. The row space of A equals the column space of AT, which for this particular A equals the column space of -A. Since A and -A have the same fundamental subspaces by part (b) of the previous question, we conclude that the row space of A equals the column space of A.

## What is column span?

The column-span CSS property makes it possible for an element to span across all columns when its value is set to all .
