I have a column of dates that are number (double format) such as 19940127 how can i convert it to matlab numeric date that corresponds to 1994/01/27?

Answer 1

One approach:

dd = 19940127;
out = datestr(datenum(num2str(dd, '%d'), 'yyyymmdd'), 'yyyy/mm/dd')

out =
1994/01/27

To get the date number, just use part of that:

out_dn = datenum(num2str(dd, '%d'), 'yyyymmdd')

EDIT — Added ‘out_dn’.

Use the datetime function with the 'ConvertFrom', 'yyyymmdd' option.
