WebGauss-Jordan Elimination is a process, where successive subtraction of multiples of other rows or scaling or swapping operations brings the matrix into reduced row echelon form. The elimination process consists of three possible steps. They are called elementary row operations: Swap two rows. Scale a row. Subtract a multiple of a row from an other. WebThe Gauss-Jordan Elimination method is an algorithm to solve a linear system of equations. We can also use it to find the inverse of an invertible matrix. Let’s see the definition first: 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 …
