How do I determine the z-transform (as a ratio of polynomials in z −1 and including any region of convergence) or inverse z-transform of the following:

Hi Chuki,

To determine the z-transform or inverse z-transform of a given function, you can use the "ztrans" or "iztrans" functions in MATLAB, respectively. These functions take a symbolic expression as input and return the z-transform or inverse z-transform of the expression.

Here is a code snippet to find the z-transform of a function:

% Define the function
syms n;
func = 3^n;

% Find the z-transform
syms z;
Ztransform = ztrans(func, n, z);

Here is a code snippet to find the inverse z-transform of a function:

% Define the function
syms z;
Ztransform = 1/(z-2);

% Find the inverse z-transform
syms n;
func = iztrans(Ztransform, z, n);

To know more about the above functions, you can refer to the below documentations:

• Inverse Z-Transform: https://in.mathworks.com/help/symbolic/sym.iztrans.html

Hope this solves your query.
