Hello, I have the following problem:
I get data of the angle of rotation of a screwdriver. Within a screw joint, the angle of rotation is reset to zero at a point in time. This can happen any number of times during a pass. Example:
1°,5°,10°,12°,1°,5°,10°,12°,1°,5°,10°,12°. The numbers are only exemplary.
I would like to merge the values now to a continuous data series. At the moment I have this code:
I hope I was able to describe the problem understandably. Many thanks
clear;
w=[1;2;3;1;2;3;1;2;3]; % Example Data
W=[];
for n=1:1:length(w)
if n==1
W(n)= 0; % 0 corresponds to: angle not reset
elseif n==max(length(w))
W(n)= 0;
elseif w(n)== w(n+1)
W(n)=0;
elseif w(n)>w(n-1)
W(n)=0;
elseif abs(w(n)-w(n-1))<-2
W(n)=0
elseif w(n)<w(n-1) % 1 corresponds to: Angle reset
W(n)=1;
end
end

The Output should be: [1,2,3,4,5,6,7,8,9]

Ran in:
w=[1;2;3;1;2;3;1;2;3];
w_new = zeros(size(w));
w_new(1) = w(1);
offset = 0;
for ii = 2:numel(w)
if w(ii) < w(ii-1)
offset = w_new(ii-1);
end
w_new(ii) = w(ii)+offset;
end
w_new
w_new = 9×1
1 2 3 4 5 6 7 8 9
