1. Fakultet

function y = fact(x)
    if x>1
        y= fact(x-1)*x;
    else
        y=1;
    end
end

2. Fibonacci

function f = fibnum(n)
    if n == 0
        f = 0;        
    elseif n == 1
        f = 1;        
    else
        f = fibnum(n-1) + fibnum(n-2);
    end
end

3. Pascals trekant

function p = pascal(n)
    p = ones(1,n);
	if n <= 2
		return
	end
	forrige_linje = pascal(n-1);
	for i = 2 : n-1
		p(i) = forrige_linje(i-1) + forrige_linje(i);
	end
 end 

4. Palindrom

function p = palindromTest(ord)
    if length(ord) == 1 || length(ord) == 0
        p = 1;
    else
        if ord(1) == ord(length(ord)) && palindromTest(ord(2:(length(ord)-1)))
            p = 1;
        else
            p = 0;
        end
    end
end

5. Exponent

function y = ten_exp(n)
    if n == 0
        y = 1;
    else
        y = 10 * ten_exp(n-1);
    end
end
