You have a logical error I think, to check if the number is in the intervall 
it should be && not ||

if (b(j) >= b(i)-bin_size && b(j) < b(i)+bin_size)

Second thing is the ; after the If () makes no sense.
Third it needs to be b(j) not b(i) which you check.

Fourth you can avoid at least one  loop by recognising that

sum(abs(b - b(i) < bin_size))

gives you the number of elements with maximum bin_size distance from the b(i) 
(you nedd to subtract 1 if you don't want to count the element b(i) itself)
