Here we explain how to perform inverse z transforms in Matlab® with the ‘iztrans()’ command. The programming example below is executed in the Matlab® command window. So you can try it in your own Matlab® software.

How To Use The ‘iztrans()’ Command In MatLab®?

>> syms x 
y = 2*x/(x-2)^2;
iztrans(y)
 
ans =
 
2^n + 2^n*(n - 1)
 
>> 

In the example above, first, we created a symbolic variable ‘x’ with the syms command in Matlab®. With this symbolic variable, we write our equation or polynomial, which is ‘y’ above. 

Then we wrote the ‘y’ inside the ‘iztrans()’ command above. Hit the ‘Enter’ key then see the result of it in the command window. 

Conclusion

So, performing inverse z transforms in Matlab® with the ‘iztrans()’ command is very simple as you see above.
