So I have to create a function that takes an input value and then generates it factorial using a recursive algorithm.
This is what I have so far, but I just can't seem to get it to work. any help would be great thanks
function y = FactRecur(n)
for n=input('give integer ')
y = n ;
if n == 0
y = 1 ;
else
y = y * FactRecur(n-1);
end
disp(y)
end

Don't ask for n.
Try this:
function y = FactRecur(n)
y = n ;
if n == 0
y = 1 ;
else
y = y * FactRecur(n-1);
end
disp(y)
Now call it, for example to find 5! :
result = FactRecur(5)
