B = (:,1:3);
C = (:,4); % Group packets restart at 0 and finish at a specific number
group = cumsum(C == 0) + double(C(1) ~= 0); % Splits the groups further
% into ones then twos then therees etc...
% [1 1 1 1 1 2 2 2 2 2 2 2 3 3 3 4 4 4]'
Bb = splitapply(@(m) {(unwrap(m/2^15*pi)*2^15/pi)}, B, group); % Splits the groups up and performs the
% caculation unwrap(m/2^15*pi)*2^15/pi
Original output input at B

The result of the algorithm can be seen below. Unfortunately, it is not operating correctly as it has a drift in the y-direction. Can anyone provide any insight into how to correct this code?
