Hello,
I have an cell array of size 3765x1(Accelerometer Data) each row contain an double array with same column size and different row size(ex. 1) 230x40, 2) 260x40, 3) 195x40 .... 3965) 312x40).
I want to apply overlap moving window with window size = 40 and 25% overlap to each of this sub-arrays. For example, in the case of 230x40 array I should approximately obtain 7 new square arrays(40x40) and remaining rows should be added to the next 260x40 array and so on. from the last 3965 array I want to remove all the remaining rows.
In the case of 230x40 => 1)(1-40)x40, 2) (30-70)x40, 3) (60-100)x40 ect.
As a result I want to get new cell array of size ~38658 containing only 40x40 square arrays obtained from above.
This is my code, but it doesn't work as i would:
Version1:
n_window = 40;
overlap_win=10;
for i = 1:length(fcell)
max_count = ceil((length(Acc{i,1})-n_window)/(n_window-overlap_win))+1;
for k = 1:max_count
for ii = 1:length(Acc{i,1})
new_data{k,1} = Acc{i,1}(1:length(CalAccGyr{i,:}(ii,:)),:)' + (1:n_window);
end
end
end
After overlap sliding window process, this cell array should not be 3965x40...
Version2:
count = 0;
for i = 1:length(fcell)
for j = 1:10:length(Acc{i,1})-40
count = count+1;
new_data{j,1} = Acc{i,1}(j+1:40+j)' + (1:40);
end
end
Version3:
n_window = 40;
overlap_win=10;
for i = 1:length(fcell)
N_max=length(Acc{i,1});
max_count = ceil((length(CalAccGyr{i,1})-n_window)/(n_window-overlap_win))+1;
n_start=1;
for count = 1:max_count
n_end = n_start + n_window - 1;
if n_end > N_max
new_data{count,1} = Acc{i,1}(n_start:N_max);
else
new_data{count,1} = Acc{i,1}(n_start:n_end);
end
n_start = n_end-overlap_win;
end
end
Please help me figure this out...
Thank you.
