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?

Start with the isbetween function, and add a separate logical vector for the device ID —
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.
