I have a column(a(:,1)) containing numbers like;
19900101
19900102
19900103
19900104
19900105
19900106
19900107
19900108
19900109
19900110
The numbers represent year(1:4), month(5:6) and daynumber(7:8).
How to I split these numbers into year, number of month and daynumber?
Thanks
Johannes

years = floor( a(:,1) ./ 10000);
months = mod( floor( a(:,1) ./ 100 ), 100);
days = mod( a(:,1), 100 );

I'd prefer this method, because it does not convert the numbers to strings and back to numbers again.

It is not clear what your "a" is. If it is a numeric array
a = [ 19900101
19900102
19900103
19900104
19900105
19900106
19900107
19900108
19900109
19900110
];
you need to convert it to a char array
a = int2str(a);
Obviously if it is already a char array, you do not need to convert it. You then need to grab the sections you want, and possibly convert them back into numbers ...
year = str2num(a(:, 1:4));
month = str2num(a(:, 5:6));
day = str2num(a(:, 7:8));
