Calculate the column space of a matrix, which is the span of its column vectors. This calculator provides the basis of the column space and related properties.

Enter your matrix values below, and the calculator will find the column space using Gaussian elimination to determine linearly independent columns.

Matrix Input

Linear Algebra Concepts

The column space is a fundamental concept in linear algebra that helps us understand the behaviour of linear transformations and systems of linear equations.

Finding the Column Space

To find a basis for the column space of a matrix A:

  1. Transform the matrix into reduced row echelon form (RREF)
  2. Identify the pivot columns in the original matrix (columns that contain leading 1's in RREF)
  3. These pivot columns from the original matrix form a basis for the column space
Rank-Nullity Theorem

For any m × n matrix A:

rank(A) + nullity(A) = n

Where:

  • rank(A) = dimension of the column space = dimension of the row space
  • nullity(A) = dimension of the null space (kernel)
  • n = number of columns in A
Applications

Column space analysis is used in:

  • Determining solvability of linear systems
  • Data compression and image processing
  • Machine learning algorithms
  • Signal processing
  • Engineering simulations

Understanding the Column Space Calculator

What Is the Column Space?

The column space of a matrix is a subspace formed by its column vectors. It helps represent solutions to linear equations. Understanding the column space is vital in Linear Algebra, as it reveals important information about the relationships between different vectors within the matrix.

How the Calculator Works

The calculator transforms your matrix into its reduced row echelon form (RREF) and identifies the pivot columns. These columns are crucial as they determine the basis for the column space. This process makes it easier to see which vectors contribute to the span of the column space.
