I found a function that creates a design matrix from a predictor matrix, x2fx. If 'interaction' is the right model for my case, then does this look right:x=...;%prediction matrix, n x pY=...;%responces matrix, n x dx=x2fx(x,'interaction');[Yrow,Ycol]=size(Y);X=cell(Yrow,1);for j=1:Yrow    X{j}=[repmat(x(j,:),Ycol,1)];end[beta]=mvregress(X,Y);-Aino
