Hello everyone, i m new to matlab as it is a part of our curriculum . i m studying DSP. actually i want to calculate and plot inverse Z -transform. below i m writing code for calculating poles and zeroes and plot it it works well, but i now want to calculate inverse of the below given program. as i m beginner, i just want that program should be basi as the above program.
thanks



NUM=input('Input the numerator polynomial');
DEN=input('Input the denominator polynomial');
TRANSF=tf(NUM,DEN);
[ZEROES POLES GAIN]=tf2zp(NUM,DEN);
disp('Poles of transfer function are:');
disp(POLES);
disp('Zeroes of transfer function are:');
disp(ZEROES);
disp('Gain of transfer function are:');
disp(GAIN);
zplane(NUM,DEN);
