Hi,
I have data, want to calculate cycles after each reset of lifetime(each cycle life hours are different),
lifeHours
0.2
3
12
18
22
0.8
1.5
2.9
5
8
11
17
1
4
5
8
13
17
23
28
Desired Output: Cycles start from 1
Cycles

Defining ‘v’ as your vector:
[~,locs] = findpeaks(-v); % Find Minima
tlocs = [1; locs; numel(v)+1]; % Define Cycle Limits
dlocs = diff(tlocs); % Cycle Lengths
Output = repelem([1 2 3], dlocs)'; % Vector Of Cycle Designations (R2015a & Later)
Cycles = [v Output]
Cycles =
0.2 1
3 1
12 1

22 1

Consider the following code:
data = [0.2 3 12 18 22 0.8 1.5 2.9 8 11 17 1 4 5 8 13 17 23 28]'
% preallocation
cycle(length(data),1) = 0
% manually mark a beginning of the first cycle
cycle(1) = 1;
for i=2:length(data)
if data(i)>data(i-1)
cycle(i) = cycle(i-1);
else
cycle(i) = cycle(i-1)+1;
end
end
cycle
The output:
>> cycle
cycle =
1
