Hi
I need to create a look up table, where i would need to specify. This will need to a manual table, where i would need to spicify the following:
Start DateTimeStamp, Stop DateTimeStamp and Device ID.
Then i would like to compare a incoming datastreams timestamp, aganist this lookup table to to NaN samples between the dates.
How can i create a table from Matlab, instead of using spreadsheet and how do you compare timestamps?

DateTime = datetime('now')+hours(0:4:150).';
DeviceID = randi(9, size(DateTime));
T1 = table(DateTime,DeviceID)
Start_DateTimeStamp = "21-Nov-2022 12:00";
Stop_DateTimeStamp = "22-Nov-2022 18:00";
Device_ID = randi(9)
Lv = isbetween(T1.DateTime, Start_DateTimeStamp, Stop_DateTimeStamp) & Device_ID==T1.DeviceID;
Query = nnz(Lv)
Result = T1(Lv,:)
Make appropriate changes to work with your data.

Nothing prevents you from organizing the file structure however it best suits the task...
Again, you've given us absolutely no context with which to work; how are we to have any idea of any specific organization or code structure that would fit?
