Understanding Gauss-Jordan Elimination

Gauss-Jordan elimination is an extension of Gaussian elimination that transforms a matrix into reduced row echelon form (RREF) through a sequence of elementary row operations.

Elementary Row Operations
  • Row Swapping: Interchanging two rows
  • Row Scaling: Multiplying a row by a non-zero scalar
  • Row Addition: Adding a multiple of one row to another row
Reduced Row Echelon Form (RREF)

A matrix is in reduced row echelon form when:

  1. All rows consisting of only zeros are at the bottom of the matrix
  2. The leftmost non-zero entry (leading entry) in each non-zero row is 1
  3. The leading entry in each non-zero row is the only non-zero entry in its column
  4. The leading entry in each non-zero row is to the right of the leading entry in the row above it
Applications
  • Solving systems of linear equations
  • Finding the inverse of a matrix
  • Computing the rank of a matrix
  • Finding the null space (kernel) of a matrix
  • Determining linear independence
