To write a MATLAB program to perform the Z-transform and Inverse Z- transform

Source code 1

clc;

clear all;

close all;

syms n;

x = n+1;

X = ztrans(x);

disp(X);

pretty(X);

 

Source code 2

clc;

clear all;

close all;

x= input('enter the sequence');

X=0;

n=length(x);

y=sym('z');

for i= 1:n

X= X+ x(i)*y^(1-i);

end

display(X);

%Inverse Z Transform

syms z;

X = z/(z - 1) + z/(z - 1)^2;

x = iztrans(X);

disp(x);
