How to Select Specific Time Intervals Over a series of time steps

3 views (last 30 days)
Hi, I have a data collected every 3 minutes for several months but now I am only interested in what happen during the day. How can I select the output between certain hours 4:00 am to 7:00 pm for every day of the data? Below is an example of the dat I am working on.
Thank you for the anticipated help.

Is the data loaded in MATLAB? If yes, you can do something like this
dts; % datetime vector;
Transp_val; % Transpiration values
hrs = hour(dts)
mask = (hrs > 4) & (hrs < 19);
filtered_dts = dts(mask);
filtered_Transp_val = Transp_val(mask);

I second Ameer's logical indexing approach. On the other hand, if this is representative of your data format, you may consider keeping these timestamped data with timetable.
Assuming you store those in a spreadsheet or CSV format, you can read the data in using readtimetable:
tt = readtimetable('dataFile.txt');
Attached is a resulting timetable from your pasted data.
Then you can do the same logical indexing Ameer suggest, while keeping the timestamp and data together in the same container:
filtered_Transp_val = tt(hour(tt.Time)>=4 & hour(tt.Time)<=19,:);
