Using Matlab, modify the matlab code solution approach by using the Matlab Detrend function.

Question 1-Determine if the signal was successfully modified to become stationary

Question 2- Is the detrended approach an improvement over the original Part 2 solution?

Given Matlab Code

y = [diff(x);0]; % Take difference between points.

for k = 1:4 % Segment signal into 4 segments

m = 250*(k-1) + 1; % Index of first segment sample

segment = y(m:m+249); % Extract segment

avg(k) = mean(segment); % Evaluate segment mean

variance(k) = var(segment);% and segment varianceend% Output means and variance with header comments

disp('Mean Segment 1 Segment 2 Segment 3 Segment 4')

disp(avg)

disp('Variance Segment 1 Segment 2 Segment 3 Segment 4')

disp(variance)
