About

The Gauss-Jordan elimination method is a systematic approach to solving linear equations, finding the inverse of matrices, and determining the rank of matrices. It transforms a matrix into its reduced row echelon form (RREF) through a series of elementary row operations, making it a fundamental technique in linear algebra.

Our Gauss-Jordan Elimination Calculator simplifies this process, allowing users to input matrices and quickly obtain results with just a few clicks. Whether you’re a student, teacher, or professional, this tool is designed to enhance your understanding of linear algebraic concepts and operations.

How to Use

Using the Gauss-Jordan Elimination Calculator is straightforward:

1. Enter the elements of the matrix in the provided input fields.
2. Select the number of rows and columns according to your matrix dimensions.
3. Click on the Calculate button.
4. View the result in reduced row echelon form, or as an inverse matrix if applicable.

This user-friendly interface allows quick calculations without tedious manual work.

Formula

The fundamental operations used in the Gauss-Jordan elimination process include:

• Row swapping, to change the order of rows.
• Row multiplication, to multiply a row by a non-zero scalar.
• Row addition, to add a multiple of one row to another row.

Through combining these operations, we aim to achieve a matrix in the form:

RREF: {1 0 … | b, 0 1 … | c, … | 0 … | d}

Where each row represents a simplified equation in the system.

Example Calculation

Let’s consider a system of equations:

• 2x + 3y = 5
• 4x + 9y = 15

The corresponding matrix is:

[2 3 | 5]

[4 9 | 15]

By applying the Gauss-Jordan elimination method, the matrix transforms to:

[1 0 | 1]

[0 1 | 1]

The solution to this system is:

• x = 1
• y = 1

This demonstrates how effectively our calculator can solve linear equations.

While the Gauss-Jordan elimination method is powerful, it does have limitations:

• It can be computationally intensive for large matrices, leading to slow calculations.
