tfdata
16-226
you can extract the numerator and denominator coefficients by typing
[num,den] = tfdata(h,'v')
num =
0 1 1
den =
1 2 5
This syntax returns two row vectors.
If you turn
h into a MIMO transfer function by typing
H = [h ; tf(1,[1 1])]
the command
[num,den] = tfdata(H)
now returns two cell arrays with the numerator/denominator data for each
SISO entry. Use
celldisp to visualize this data. Type
celldisp(num)
and MATLAB returns the numerator vectors of the entries of H.
num{1} =
0 1 1
num{2} =
0 1
Similarly, for the denominators, type
celldisp(den)
den{1} =
1 2 5
den{2} =
1 1
