how to use numerator and denominator (N,D) of the output transfer function yv. where yv is 16 tranfer functions. i want to see N and D and use them in another process.
for i=1:4
for j=1:4
gvi(i,j)=tf(N(i,:),D(j,:))
yv(i,j)=series(yc,gvi(i,j))
end
end
[N,D]= tfdata(yv)%%%% this line doesn't show the content of N and D

Use it inside the loops, preallocation is recommended for the variables.
