Is there something like 'array colon'? in other words how can I apply colon operator to all the elements of an array (please read the text below so my question will make sense)?

A = [1 10 16 23];
A-3:A+2 will result in [-2,-1,0,1,2,3]; In other words colon operates only on the first element of array A. However I want to apply A-3:A+2 on all the elements of A; I know I can get this by a loop, like :
u=[];for i=1:4, u=[u,A(i)-3:A(i)+2]; end
However I wonder if there is a way to do this without using loop. (The actual array I am working with is too long to loop through it.)
This sounds like a super simple question but I have no ides how to do it in a simple way (other than looping).
I so much appreciate any help.

do you mean a division
A = [1 10 15 23];
(A-3)./(A+2 )

I'm not sur what you need
A = [1 10 15 23];
unique(cell2mat(arrayfun(@(x) x-3:x+2,A,'un',0)))
