Hi all can anyone please help with the conversion of date from yyyymmddHHMMSS format to yymmddHHMMSS format.
for example I want to change column 1 in the following dataset: (e.g row 1 shoud be 200723000000)
'2020,07,23,00,00,00' -0.800000000000000
'2020,07,23,00,00,10' -0.800000000000000
'2020,07,23,00,00,20' -0.700000000000000
'2020,07,23,00,00,30' -0.700000000000000
'2020,07,23,00,00,40' -0.700000000000000
'2020,07,23,00,00,50' -0.800000000000000
'2020,07,23,00,01,00' -0.700000000000000
'2020,07,23,00,01,10' -0.700000000000000
'2020,07,23,00,01,20' -0.700000000000000
'2020,07,23,00,01,30' -0.600000000000000
'2020,07,23,00,01,40' -0.600000000000000
'2020,07,23,00,01,50' -0.600000000000000
'2020,07,23,00,02,00' -0.500000000000000
'2020,07,23,00,02,10' -0.500000000000000

vec = datevec( '2020,07,23,00,00,00', 'yyyy,mm,dd,HH,MM,SS' );
datestr( vec, 'yymmddHHMMSS' )
or did you mean
datestr( vec, 'yy,mm,dd,HH,MM,SS' )

First a couple of comments
- format your question and comments so that they are easier to read an copy
- keep test cases small and to the point, e.g. there is no need for a large text file
- read answers and comments carefully and tell if you don't understand
I added a format string (I'm om R2018b)
%%
t = readtable('20200724T000000.txt');
dates = t.Var1;
durations = t.Var2;
T = table(dates, durations);
fullDateTime = dateshift(T.dates,'start','day') + T.durations;
fullDateTime.Format = 'yyyyMMddHHmmSS';
T.DateTime = datestr(fullDateTime,'yymmddHHMMSS');
%%
datevec(T.DateTime(1:2,:),'yymmddHHMMSS')
The value of T.DateTime is a character array, e.g.
T.DateTime(1:2,:)
Wasn't there a string like 1.0e+4 above the output
format short
magic(4).*1e-6
I fail to reproduce your output
datevec(T.DateTime(1:2,:))
