hello,
i am trying to get a function that can find the divisiblity of 1 to 25 to 3 and 5
1 is NOT divisible by 3 or 5
2 is NOT divisible by 3 or 5
...
24 is divisible by 3
25 is divisible by 5
i havnt got any function done becuase i am bad at matlab, but i have an idea of using function and using loop to loop the divisibility of each number as they keep adding one from the last one

If x can by divided by y:
rem(x, y) == 0
Or:
x / y == round(x / y)
Another apporach is to calculate the list of multiples of 3:
m3 = 3:3:25
allNumbers = 1:25
Now ismember(allNumbers, m3) replies TRUE, if the number can be divided by 3.
