How to extract latitude and longitudes from a table given the timestamp range?

Hello, I'm currently using a time table and want to have the user give a start time and end time then store them in variables. Once given, I want to use the timetiable to access a list of latitude and longitude values given in between those times and plot it. I'm still new to MATLAB and unsure how to approach this is ui.app designer.

I would use isbetween to create an index of the table rows that are between the lower and upper times.

I would then use that index to extract the specific variable values I wanted from the table. See Accessing Data in Tables for this.

Use a timerange object as the row index into your timetable.

Time = datetime({'12/18/2015 08:00:00';'12/18/2015 10:00:0';'12/18/2015 12:00:00';...
                 '12/18/2015 14:00:00';'12/18/2015 16:00:00';'12/18/2015 18:00:00'});
Temp = [37.3;39.1;42.3;45.7;41.2;39.9];
TT = timetable(Time, Temp)

TT = 6x1 timetable
            Time            Temp

R = timerange('12/18/2015 09:00 AM', '12/18/2015 05:00 PM')

R = 
	timetable timerange subscript:

		Select timetable rows with times in the half-open interval:
		  Starting at, including:   18-Dec-2015 09:00:00
		  Ending at, but excluding: 18-Dec-2015 17:00:00

TT(R, :)

ans = 4x1 timetable
            Time            Temp
