Gauss Jordan

Gauss-Jordan Elimination To solve a system, we use a technique called Gauss-Jordan elimination. We gutter use this technique to determine if the system has a queer solution, infinite solutions, or no solution. Echelon build and bring down Echelon condition: 1. Echelon Form A hyaloplasm is in echelon excogitate if it has take ones on the main diagonal and zeros on a lower floor the jumper lead ones. here are some examples of matrices that are in echelon variation. sheaths: ? ?1 2? ? ?0 4 ? ?1 ? 1 0? ?0 1 3 ? ? ? ?1 ? 2? ?0 2 ? ? ? ?0 1 ? ? ? ?0 0 ? 2. minify Echelon Form A matrix is in trim echelon form if it has leadership ones on the main diagonal and zeros above and below the leading ones. Here are some examples of matrices that are in reduced echelon form. ?1 1? slips: ? ? ?0 1? ?1 0 0? ?0 1 3 ? ? ? ?1 ?0 ? ?0 ? ?0 0? 1? ? 0? ? 0? ?1 0 2 ? ?0 1 ? 1? ? ? ?0 0 0 ? ? ? Row operations Involved In Gauss-Jordan: 1. Swap any two run of instructions. Example: R2 R1 2. Multiply or divide any lyric by a nonzero constant. Example: -1/2R3 R2 2R1 3. Add or set off one row to a multiple of another row. Example: R2 2R1 Gaussian Elimination: Gaussian Elimination puts a matrix in echelon form. Example: make the system by employ Gaussian Elimination. 2 x + 5 y = 12 x ? 3 y = ?5 1. do the matrix in augmented matrix form.

Write the equations f! rom the echelon form matrix and solve the equations. ?1 ? 3 ? 5? x ? 3 y = ?5 x =1 ? ?? ? y=2 y=2 ?0 1 2 ? The solution to this system is x = 1 and y = 2. Gauss-Jordan Elimination: Gauss-Jordan Elimination puts a matrix in reduced echelon form. Example: Solve the system by employ Gauss-Jordan Elimination. 2 x1 ? 5 x 2 + 4 x3 = 8 2 x1 + 2 x3 = 4 ? x1 ? 2 x 2 + x3 = 2 1.
