Gauss-Jordan elimination method By Dr. Guillaume Leduc Gauss-Jordan elimination method The Gauss-Jordan elimination method is a method to simplify a matrix. We say that this method is a method to " reduce " the matrix. Here reduce means to simplify it. Step 0: Move to the Top Row The first step is to "spot" the first row at the top of the matrix Step 1: Need 1 Locate the first element in the row which is not zero. Change this element for a 1. How should you proceed? You can do this the way you want using any combination of the 3 row operations, as long as all your operations involve only rows which are located below. In other words, to get the 1 forget any of the rows above. Basically, there are 3 possibilities. 1. Multiply the row by a constant to change the element into a 1. 1 k R i R i This is the most normal way to proceed. 95% of the time you will use that method. If you want to, you can use that method all the time, it is up to you!
