Then, the aim of the ACMA method is to factorise X to get back [??] and [??] or alternatively find a beamformer matrix W, where [??] = [W.sup.H]X with some phase ambiguity.
Furthermore in Year 8 students should "extend and apply the distributive law to the expansion of algebraic expressions" and "factorise algebraic expressions by identifying numerical factors" (ACARA, 2014).
In the end of the XIXth century, Hurwitz computed the number of ways to factorise in the symmetric group [S.sub.n] a permutation of given cyclic type [lambda] into a product of a minimal number of transpositions which generate a transitive subgroup.
While, the budgeted growth may appear low compared to the 2013 budget, one has to factorise that the actual growth in 2013 was around five per cent and this is the highest over the last three years."
