| Basis (linear algebra) - Wikipedia, the free encyclopedia |

| | When we want to describe the **matrix** of a linear transformation and in some other situations, it is convenient to list the basis vectors in a specific order. |

| | We then speak of an ordered basis, which we define to be a sequence (rather than a set) of linearly independent vectors that span V. |

| | Since the above **matrix** has a nonzero determinant, its columns form a basis of R |
