Extracting the data after the threshold point
显示 更早的评论
Hi everybody,
I am looking for extracting series of data after a threshold.
I have set the threshold at 1.4 and looking to extract the data after(data from x axis).
X axis is number of cycle
y axis is capacity
Kindly suggest an approach or link for reference, hope my question is understandable.

So do you want data starting with x=118 or 120? If the threshold is 1.4, why are there are few red dots before y ever gets down to 1.4, as if you wanted to select those?

If I understand correctly what you want to do, this will work:
Capacity_Thresh = Capacity(Capacity <= 1.4);
NrCycles_Thresh = Number_Of_Cycles(Capacity <= 1.4);
This will detect and save only those values where ‘Capacity’ is less than or equal to ‘Threshold’. If you want to detect the first index that ‘Capacity’ is less than or equal to ‘Threshold’, and save everything after that:
Thrsh1 = find(Capacity <= 1.4, 1);
Capacity_Thresh = Capacity(Thrsh1:end);
NrCycles_Thresh = Number_Of_Cycles(Thrsh1:end);
You may need to experiment to get the result you want.
