I have a large file containing data for one whole month. I have two separate column vectors of data where one is timestamp in the form '2016-02-01 00:19:09 ' and second vector is Vtec data. I want to analyse the data by days. I want to select the data for first 4 days and with corresponding Vtec data and then plot the graph and then next 4 days until I complete the month. I was using this code but it is giving me a error
idx = ( '2016-02-01 00:19:09 '<= TM2 & TM2 <'2016-02-05 00:00:00 ' );
Any suggestions on this matter will be highly appreciated.

Convert your dates to datetime and use isbetween.
idx = isbetween(TM2,datetime(2016,02,01,00,19,09),datetime(2016,02,05,00,00,00));
