create a code where there is a test data, and all the segments of the test data between y = 0 to y = 0.2, as well as their start and end points, would be obtained in matlab

main.m
% generate test data
y = rand(1, 1000);

% define threshold values for segmentation
y_min = 0;
y_max = 0.2;

% segment data based on threshold values
idx = (y > y_min) & (y < y_max);
segments = split(find(diff([0 idx 0]) ~= 0), diff([0 idx]));

% get start and end points of segments
segment_start = segments(:,1);
segment_end = segments(:,2);

% plot original data and segmented data
subplot(2,1,1)
plot(y)
xlabel('Sample')
ylabel('y')
title('Original Test Data')

subplot(2,1,2)
plot(y)
hold on
plot(segment_start, y(segment_start), 'ro', 'MarkerSize', 5)
plot(segment_end, y(segment_end), 'rx', 'MarkerSize', 5)
xlabel('Sample')
ylabel('y')
title('Segmented Test Data')
legend('Data', 'Start Points', 'End Points')
