MATLAB: How to make a function that checks the divisibility of a given number, n, by 3, 5, 7, and 11.

Question

I am trying to write a function div – divisibility(n) that checks the divisibility of a given number input n, by 3, 5, 7, and 11 for a hw problem. The problem requires that my output be a logical vector output of 4 elements corresponding to the divisibility by 3, 5, 7 and 11, respectively. For example, the output of divisibility(14) would be [0 0 1 0]. I have figured out how to write a function that gives a single output, but I do not know how to write a function that outputs a logical vector.

All I have so far is:

function div = divisibility(a)

div = rem(a,3)

end

Answer 1

This works:

divisibility = @(x) rem(x, [3 5 7 11]) == 0;
div = divisibility(14)

producing:

div =
       0     0     1     0
