sum of all multiples of 3 or 5 upto n

List all the natural numbers up to 10 that are multiples of 3 or 5, we get 3, 5, 6, 9 and 10. The sum of these multiples is 33. Write a function that returns the sum of all the multiples of 3 or 5 up to n where n is a positive integer and the only input argument of the function.

And what have you tried? This is your homework. Answers is not here to do your homework. If you have an actual question about MATLAB, then ask it. But you need to make some effort, as that is how you will learn.

To expand on John's answer, I would recommend reading this post that provides some details on how to properly ask for help on the MATLAB Answers site. We strive to keep the questions answered on this site specific and MATLAB-related.
