lu(A)
performs LU factorization of a matrix. So, you can get upper triangular matrix from there. Not sure though if it performs Gauss reduction
[L,U,P] = lu(A);

With rref you will produce the reduced row echelon form, see
doc rref
But a non-reduced form is not unique. See for instance wikipedia: http://en.wikipedia.org/wiki/Gaussian_elimination. You can multiply individual rows with a scalar and/or add rows to other rows. It is in echelon form as long as it is upper-triangular.

yes ,it would be a good idea, especially since Lay's Linear Algebra seems to prefer Matlab

it should be implemented the same way TI does in their calculators, for consistency
