Problem Statement

Show how to compute the reduced row echelon form (a.k.a. row canonical form) of a matrix. The matrix can be stored in any datatype that is convenient (for most languages, this will probably be a two-dimensional array). Built-in functions or this pseudocode (from Wikipedia) may be used: For testing purposes, the RREF of this matrix: is:

Let's start with the solution:

#lang racket
(require math)
(define (reduced-echelon M)
  (matrix-row-echelon M #t #t))  

(reduced-echelon
 (matrix [[1 2 -1 -4] 
          [2 3 -1 -11]
          [-2 0 -3 22]]))
