Question

No loops can be used and must only use functions that are built into matlab, aka no toolboxes

FACTORS All Factors of an Integer

FACTORS(N) returns all the factors of the positive integer N.

For example:

FACTORS(60) returns the 2 X 6 array

[ 1 2 3 4 5 6

60 30 20 15 12 10]

FACTORS(25) returns the 2 X 2 array [ 1 5

25 5]

FACTORS(7) returns the 2 X 1 array [1

7]

If N is an empty array, an empty array is returned. If N is NaN, NaN is  returned.

If N is missing or not a real, positive, numeric, integer-valued scalar

having value less than flintmax, an error string is returned by the

function error that states what is wrong with the input argument.

No For or While loops permitted.

No extraneous output to the Command Window.

Hello,
Please find the answer attached as under. Please give a thumbs up rating if you find the answer useful! Have a rocking day ahead!

************ MATLAB function file ***********

function f = factors(N)
if (N==[])
f=[];
elseif(N==NaN)
f=NaN;
elseif(nargin==0)
fprintf('No argumenst supplied!\n');
elseif(N<0 || floor(N)~=N)
fprintf('The supplied number is not in specified format\n');
else
K=1:N;
f = K(rem(N,K)==0);
end
end

**************** End of code ************

sample output

>> factors(7)

ans =

1 7

>> factors(0.7)
The supplied number is not in specified format>>
