http://www.betsymccall.net/prof/courses/spring12/cscc/268matrix_ops.pdf WebDoing elementary row operations corresponds to multiplying on the left by an elementary matrix. For example, the row operation of "new R2 = R2 - 3R1" is produced on a 3 by n matrix when you multiply on the left by ( 1 0 0 − 3 1 0 0 0 1). Column operations, on the other hand, are produced when you multiply by a matrix on the right hand side.

WebIt relies upon three elementary row operations one can use on a matrix: Swap the positions of two of the rows Multiply one of the rows by a nonzero scalar. Add or subtract the scalar multiple of one row to another row. For an example of the first elementary row operation, swap the positions of the 1st and 3rd row.
