How to create an array that picks every 3 numbers out of 5

Hello,

I have a vector that includes degrees of freedom (numbers) from 1 to 665 and i want a function that makes an array to pick every 3 last numbers out of every numbers as a colomn and next colomn with zeros.

To make it more clear:

from 1 to 5 i want 3 4 5, then from 6 to 10, i want 8 9 10 and so on until 665. see below

C=[3 0;
   4 0;
   5 0;
   8 0;
   9 0;
   10 0];

a = reshape(1:665,5,[]);
a(1:2,:) = [];
a = reshape(a,[],1);
a(:,2) = 0;
