Recursive Factorial Function Evaluation

I'm trying to make a recursive function to test factorials that will check for a variable that is a non-negative single argument (it will display an error using the error function if not). How should I go about doing this?

clc
clear all
%% Factorial of the number
n = 8;
out = facto(n);
%% Factorial function
% Create a function for factorial
function f = facto(num)
% FACTO Summary of this function goes here
% factorial of the n
% It is a recursive function call
% if n does not reaches 0. This mean n is either negatve number or
% decimal number. The problem of out of memory occurs. The likely cause
% is an infinite recursion with the program. The problem never converges.
if ~isscalar(num) || num ~= fix(num) || num < 0
error('non-negative integer scalar input expected')
end
if num == 0
f = 1;
else
f = num*facto(num-1);
end
end
