WITH_DASH_DASH The factor matrix

S(1,2,1) %<REPLACE_WITH_DASH_DASH Generate the element of index (1,2,1) from the factorization

%% Subscripted assignment for symktensors
% Subscripted assignment can be used to change the order, weight vector, or
% factor matrix of a symktensor. First, we change the weight vector
S.lambda = [1;1]

%%
% Next, we alter the factor matrix. U can be used instead of |X| in the 
% notation that follows
S.X = [1 0; 0 1; 1 0; 0 1]
%%
% Lastly, we alter the order. This changes $m$,
