Syntax
tlim = ncdatelim(files, var)
Description
tlim = ncdatelim(files, var)reads data from the file or files indicated by the string/character array or cell array of stringsfiles. It reads the first and last value of the time variablevar, assuming that variable uses a standard (i.e. gregorian) calendar and includes a CF standard units attribute (seencdatereadfor more details). The returnedtlimvariable is an n x 2 datetime array, where n is the number of files queried.
Example
Read date limits in each of the example netCDF files included with this toolbox:
cdtpath = fileparts(which('cdt')); files = {...fullfile(cdtpath,'cdt_data',“ERA_Interim_2017.nc”) fullfile(cdtpath,'cdt_data','ERA_Interim_2017a.nc') fullfile(cdtpath,'cdt_data','ERA_Interim_2017b.nc') fullfile(cdtpath,'cdt_data','ERA_Interim_2017c.nc')}; tlim = ncdatelim(files,'time')
tlim = 4×2 datetime array 2017-01-01 2017-12-01 2017-02-01 2017-02-01 2017-03-01 2017-03-01 2017-04-01 2017-04-01
