This extension of Gauss' Method is called Gauss-Jordan reduction. It gives us a more refined, specialized matrix form. matrix is in reduced echelon form if, in addition to being in echelon form, each leading entry is a one and is the only nonzero entry in its column Forward elimination of Gauss-Jordan calculator reduces matrix to row echelon form. Back substitution of Gauss-Jordan calculator reduces matrix to reduced row echelon form. But practically it is more convenient to eliminate all elements below and above at once when using Gauss-Jordan elimination calculator Ri +αRj means: Replace rowi with the sum of rowiandαtimes rowj. The Gauss-Jordan elimination method to solve a system of linear equations is described in thefollowing steps. Write the augmented matrix of the system. Use row operations to transform the augmented matrix in the form described below, which iscalled thereduced row echelon form(RREF) [Gauss-Jordan Elimination] For a given system of linear equations, we can find a solution as follows. This procedure is called Gauss-Jordan elimination. Write the augmented matrix of the system of linear equations. Use elementaray row operations to reduce the augmented matrix into (reduced) row echelon form Perform the Gauss-Jordan elimination (reduce completely) of $$\left[\begin{array}{cc|c}1 & 3 & 14\\7 & -1 & 10\end{array}\right]$$$. Solution Subtract row $$1$$$ multiplied by $$7$$$from row $$2$$$ : $$R_{2} = R_{2} - 7 R_{1}$$$The Gauss Jordan Elimination, or Gaussian Elimination, is an algorithm to solve a system of linear equations by representing it as an augmented matrix, reducing it using row operations, and expressing the system in reduced row-echelon form to find the values of the variables A variant of Gaussian elimination called Gauss-Jordan elimination can be used for finding the inverse of a matrix, if it exists. If A is an n × n square matrix, then one can use row reduction to compute its inverse matrix, if it exists. First, the n × n identity matrix is augmented to the right of A, forming an n × 2n block matrix [A | I] To convert any matrix to its reduced row echelon form, Gauss-Jordan elimination is performed. There are three elementary row operations used to achieve reduced row echelon form: Switch two rows. Multiply a row by any non-zero constant. Add a scalar multiple of one row to any other row https://drive.google.com/file/d/1_nGnEFrNfPUweHcMkr-LyoVFMn0ZsPzY/view?usp=drivesd Fascinating article on the history of Gauss-Jordan reduction Permalink Submitted by ddrucker@wayne.edu on Thu, 2014-07-31 02:20 Discusses methods and notations used by Gauss, Wilhelm Jordan, and B. Once a system is expressed as an augmented matrix, the Gauss-Jordan method reduces the system into a series of equivalent systems by using the row operations. This row reduction continues until the system is expressed in what is called the reduced row echelon form After performing Gaussian elimination on a matrix, the result is in row echelon form, while the result after the Gauss-Jordan method is in reduced row echelon form The purpose of Gauss-Jordan Elimination is to use the three elementary row operations to convert a matrix into reduced-row echelon form. A matrix is in reduced-row echelon form, also known as row canonical form, if the following conditions are satisfied: All rows with only zero entries are at the bottom of the matri We present an overview of the Gauss-Jordan elimination algorithm for a matrix A with at least one nonzero entry. Initialize: Set B 0 and S 0 equal to A, and set k = 0. Input the pair (B 0;S 0) to the forward phase, step (1). Important: we will always regard S k as a sub-matrix of B k, and row manipulations are performed simultaneously on the sub-matrix Thanks to all of you who support me on Patreon.

The Gauss Jordan algorithm and flowchart is also similar in many aspects to the elimination method. Compared to the elimination method, this method reduces effort and time taken to perform back substitutions for finding the unknowns 高斯－若尔当消元法（英语：Gauss-Jordan Elimination），或译为高斯-约旦消元法，简称G-J消元法，是数学中的一个算法，是高斯消元法的另一个版本。它在线性代数中用来找出线性方程组的解，其方法与高斯消去法相同。唯一相异之处就是这算法产生出来的矩阵是一个简化行梯阵式，而不是高斯消元法. Gauss-Jordan reduction is an extension of the Gaussian elimination algorithm. It produces a matrix, called the reduced row echelon form in the following way: after carrying out Gaussian elimination, continue by changing all nonzero entries above the leading ones to a zero. The resulting matrix looks something like
