Formula Used in “Gauss-Jordan Elimination Calculator”
The Gauss-Jordan elimination method is an algorithm used for solving systems of linear equations. The standard formula used in the Gauss-Jordan Elimination Calculator can be represented in a stepwise form as follows:
Ax = b
Where:
- A is the matrix of coefficients
- x is the column vector of variables
- b is the column vector of constants
Step-by-Step Breakdown of the Formula
To understand how to solve the equation Ax = b, it’s essential to break down each component:
- A: The coefficient matrix containing the coefficients of the variables in the system of equations.
- x: The unknown variable vector that we aim to solve.
- b: The constants vector representing the results of the equation.
The goal of the Gauss-Jordan elimination process is to manipulate the augmented matrix [A|b] into reduced row echelon form.
Example Calculation
Let’s take a real-world example to apply the Gauss-Jordan elimination method.
Consider the following system of linear equations:
- 2x + 3y = 8
- 4x + y = 10
This can be represented in augmented matrix form, where:
[A|b] = [ 2 3 | 8 ]
[ 4 1 | 10 ]
| Step | Matrix [A|b] |
|---|---|
| Initial Matrix | [ 2 3 | 8 ] [ 4 1 | 10 ] |
| R1 ⇔ 1/2 R1 | [ 1 3/2 | 4 ] [ 4 1 | 10 ] |
| R2 ⇔ R2 – 4R1 | [ 1 3/2 | 4 ] [ 0 -5 | -6 ] |
| R2 ⇔ -1/5 R2 | [ 1 3/2 | 4 ] [ 0 1 | 6/5 ] |
| R1 ⇔ R1 – (3/2)R2 | [ 1 0 | 1/5 ] [ 0 1 | 6/5 ] |
In the final augmented matrix, we find:
- x = 1/5
- y = 6/5
Thus, the solution to the system of equations is:
- x = 0.2
- y = 1.2
This illustrates how the Gauss-Jordan elimination calculator can streamline complex calculations into manageable steps, providing solutions efficiently for various linear equations.
