Function script
function []=stable(b,a)
p=roots(a);
if abs(p)<1
disp('The system is stable')
else
disp('The system is unstable')
end
end
To call the above script
>>b=[2 1];
>>a=[1 -0.4 0.6];
>>stable(b,a);
The system is stable
>>b=[1 0.5 2];
>>a=[1 1 -1];
>>stable(b,a)
The system is unstable

5. (12 points) Create the following signal in Matlab: x[n] = u(n) - u[n-6] a. Mathematically compute yi[n] = x[n] * x[n] where * means convolution. Now use the conv command to perform the convolution. Graph x[n) and the resulting y(n), both over the interval Osns 20. How many non-zero terms does y(n) have? Does your computational result agree with the Matlab result? b. Repeat a. but this time with yz[n] = x[n]*h[n)...

a) Write MATLAB function that accepts a positive integer
parameter n and returns a vector containing the values of the
integral (A) for n= 1,2,3,..., n. The function must use the
relation (B) and the value of y(1). Your function must preallocate
the array that it returns. Use for loop when writing your code.
b) Write MATLAB script that uses your function to calculate the
values of the integral (A) using the recurrence relation (B), y(n)
for n=1,2,... 19...

Task 4.12 Using the command roots calculate the solutions of the equations 23 + 2a +r+1= 0 and – 2x + 25 + m2 = 4. Here you need to be careful that the coefficients of the polynomials are entered correctly as vectors. Solution 4.12 The roots can be calculated using the inline code roots([1 1 1 1]) and roots ([1 0 0 1 -2 -4]).
