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 cut back Echelon condition: 1. Echelon Form A intercellular substance is in echelon bring in if it has take ones on the main diagonal and zeros under the lead ones. here are some examples of matrices that are in echelon take a hop. sheaths: ? ?1 2? ? ?0 4 ? ?1 ? 1 0? ?0 1 3 ? ? ? ?1 ? 2? ?0 2 ? ? ? ?0 1 ? ? ? ?0 0 ? 2. lessen Echelon Form A intercellular substance 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? pillow 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 trading trading operations Involved In Gau ss-Jordan: 1. Swap any two cross of instructions. Example: R2 R1 2. Multiply or divide any lyric by a nonzero constant. Example: -1/2R3 R2 2R1 3. Add or withhold 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 apply Gaussian Elimination. 2 x + 5 y = 12 x ? 3 y = ?5 1. do the matrix in augmented matrix form.

Write the equations from 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 victimization Gauss-Jordan Elimination. 2 x1 ? 5 x 2 + 4 x3 = 8 2 x1 + 2 x3 = 4 ? x1 ? 2 x 2 + x3 = 2 1.
