% This example illustrates the use of the function "rf2lfr" % that transforms the matrix NDv = [N;D] to sys = N*D^(-1) % Realization of NDv lfrs Int x y z NDv = [1+x*Int x*y+z;0 x^2*Int^2;1+Int 0;0 2+x*y*Int]; % Then we apply the transformation "ndv2lfr" sys = rf2lfr(NDv); % In order to check the results, we generate this object in % an alternative way N = [eye(2,2) zeros(2,2)]*NDv; D = [zeros(2,2) eye(2,2)]*NDv; sys2 = N*D^(-1); % Comparison size(sys) size(sys2) distlfr(sys,sys2) % The function "rf2lfr" prevents augmenting the size of the % Delta-matrix.
