what is the problem?

Write a program that will implement the function ?(?) = { ? 2 − 7, ? < 9 ?(? − 10), ? ≥ 10 where ? is an integer and ? ≥ 0. Using your program, graph ?(?) from ? = 0 to ? = 99 using stem().

my while loop is not under the else n>=10 what is the problem?

i=0
for n=0:99
	if n<9
    i=i+1
    f(i)=(n.^2 - 7)
    

	elseif n==9
	f(n)=NaN
    
    
	else n>=10
    i=i+1
	f(i)=(n-10) 
    
    while f(i)>9
            f(i)=n-10
    end
            if f(i)<9
            i=i+1
            f(i)=(n.^2 - 7)
        end
    end 
end

f = @(x) 2*(x - (x >= 10)*10) - 7;

where will i put that
