Gauss-Jordan Elimination Calculator

What is Gauss-Jordan Elimination?

Gauss-Jordan Elimination is a mathematical method used to solve systems of linear equations. This method transforms a given matrix into its Reduced Row Echelon Form (RREF). By performing a series of row operations, the matrix is simplified to reveal solutions to linear equations or to determine if a solution exists.

Key steps in Gauss-Jordan Elimination include:

• Normalizing rows so that pivot elements become 1.
• Eliminating other elements in the pivot's column to create zeros above and below the pivot.
• Reducing the matrix to its final simplified form (RREF).

Frequently Asked Questions

What is Reduced Row Echelon Form (RREF)?

Reduced Row Echelon Form (RREF) is a simplified form of a matrix where each row has a leading 1, and all other elements in the leading 1's column are zeros. It is the final result of Gauss-Jordan elimination.

Can this calculator solve rectangular matrices?

Yes, the calculator handles rectangular matrices (e.g., 2×3, 3×2) in addition to square matrices. It will reduce the matrix to its RREF, which can help determine if solutions exist.

What if my matrix contains decimals or fractions?

The calculator supports both decimals and fractions as input. It performs all operations with precision and displays results rounded to two decimal places.

What happens if a pivot element is zero?

If a pivot element is zero, the calculator automatically swaps rows or moves to the next column to continue the elimination process. It ensures the correct result whenever possible.
