finding divisibility in every number from 1 to 25

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.
