I have data which supposed to look like waves. But for some reasons, the lines are not continuous.
I have attached the data and also the figure. I marked the figure with red to show how the data supposed to look like.
Anyone has an idea of how to fix that?

It's not perfect, but it might be sufficient. That's up to you. Play with the different values for dipreset. You might want to smooth the several samples around the 'entry' and 'exit' points.
data = load('task.mat');
task = data.task;
% get the location of the peaks
[pks,locs] = findpeaks(task,'MinPeakHeight',15);
% show the data with the identified peaks
% this will fail if there are not an even number of peaks
locpairs = reshape(locs,2,);
task2 = task; % temporary duplicate
for k = 1:size(locpairs,2)
% get the locations between the first dip
diplocs = locpairs(1,k):locpairs(2,k);
dipval = task(diplocs); % get the values
% get reset value
% dipreset = min(dipval([1 end]));
% dipreset = mean(dipval([1 end]));
dipreset = dipval(1);
% reset dipval
dipval = abs(dipval - dipreset) + dipreset;
task2(diplocs) = dipval; % store result
% view the output
