RREF(matrix)
This function takes an augmented matrix of size n by n+1 and transforms it
into reduced row echelon form, with the final column containing the solution.
Eg.
The system of equations
is written as the augmented matrix
which is then stored as a 3x4 real matrix M1.
We now use the function RREF to change this
to reduced row echelon form and store it as
M2.
