I have a matrix with the number of days converted using datenum(). Now I want to convert back to the original date, but the result is wrong.The code is as follows:
day=[737433;737445;737457;737469;737481;737493;737505]
value=datestr(day(1:7),'yyyymmdd');
value=str2num(value);
The execution result is:
value=[101;102;103;104;105;106;107];
actually the results should be
[20190108;20190120;20190201;20190213;20190225;20190309;20190321]
How should I solve this problem? Thank you

I cannot reproduce that. I get what the reults should be (in R2020a):
day=[737433;737445;737457;737469;737481;737493;737505];
value=datestr(day(1:7),'yyyymmdd')
value=str2num(value)
producing:
value =
7×8 char array
'20190108'
'20190120'
'20190201'
'20190213'
'20190225'
'20190309'
'20190321'
and:
value =
20190108
20190120
20190201
20190213
20190225
20190309
20190321
