How to extract the first four and last four digits of all numbers of an array where each number is of 12 digits?

32 views (last 30 days)
I have an array of over 200,000 numbers. Each of these numbers is of 12 digits. I want to extract and form another array with: (1) the first four digits of the original array, (2) the last four digits of the original array. How can it be done?
For example if one of the numbers of the array is 123456789012, then the output to (1) should be "1234" and output to (2) should be "9012".

Try this
% this is my example data
num=[152012073637; ...
325081863583; ...
841721647389; ...
648968298758; ...
346301193257; ...
595880316669];
numhead=floor(num/1E8)
numtail=mod(num,1E4)
the results are:
numhead =
1520
3250
8417
6489
3463
5958
numtail =
3637
3583
