Develop a MATLAB function divisibleBy$3(N)$ to determine if a given integer $N$ is divisible by $3$ using the following rule: if the sum of the digits is

divisible by $3,$ then the integer is divisible by $3.$

Only integer values should be considered valid inputs. Create a check of $N$ for floating point values and give a warning if one is input.

Make a test script that calls your function repeatedly and checks the results. Use a simple mod $($N$,3)$ function call to check the result, which will be $0$ if

divisible by $3.$ Create a print statement to report the result of each $N$ examined.

In your test script call your function with a non$-$integer $($like $4\mathrm{.}56$; it should give a warning$)$ and the odd numbers $951-1001.$

Capture the results in the command window with a screenshot.
