Please write a MATLAB function that finds all the divisors b

Please write a MATLAB function that finds all the divisors between 2 and 20 of and integer. Your function header should be

function div=finddivisor(a)

where the input a is an integer, the output div is a vector that contains all of the divisors of a that are between 2 and 20.

For example, if the input is 42, its divisors between 2 and 20 are 2,3,6,7,14 (21 is larger than 20 so it is not included). The output should be

div=[2 3 6 7 14]

MATLAB Code:

function [div] = finddivisor(a)
j=1;
for i=2:20
    r = rem(a,i);
   if r==0
       xx(:,j)=i;
       j=j+1;
   end
end
div=xx
end

sample output

>> finddivisor(42)

div =

2 3 6 7 14
