Hello all
I have a raw of data with 16 digits like 0799569419940319, the last 8 digits are the year, the month and the day. How can I split the cells to extract the year and month and day?

Consider:
n = 0799569419940319;
ns = num2str(n);
dn = ns(end-7:end) % Date Segment
dn = '19940319'
nn = ns(1:end-8) % Number Segment
nn = '7995694'
DT = datetime(dn, 'InputFormat','yyyyMMdd') % 'datetime' Vector
DT = datetime
19-Mar-1994
I hav no idea what the rest of these numbers are, so I cannot generalise this and so am not posting this as an Answer.

The leading zero let me assume, that this is not a number, but a CHAR vector. But if it is really a number:
n = 0799569419940319;
day = rem(n, 100)
day = 19
month = rem(floor(n / 100), 100)
month = 3
year = rem(floor(n / 10000), 10000)
year = 1994
