>> a = [-0.75 0.125];
b = [0 0.25];
n = 0:1:20;
x0 = 0;
y0 = [0 0];
x = [ones(1,21)];
y = recur(a,b,n,x,x0,y0);
stem (n,y);

xlabel('n')
ylabel('y')
Unrecognized function or variable 'recur'.

Hello Michael Jaskulski ,
As per my understanding, you have encountered error: Unrecognized function or variable 'recur'.
Please note that, there is no in-built function ‘recur’ in MATLAB R2023a. Define the function in an m-file and call the function using your own inputs and store the output from ‘recur’ in the variable ‘result’.
For more details about ‘recur’ function, you can refer the following document:
https://www.mathworks.com/matlabcentral/answers/1743585-recur-m-function
In case you further require a more specific solution tailored to your case, you can provide more information about it.
I hope it helps!
