Recursive Function in Matlab (Help)

"My code block does recursion. It's not a "recursive function", as in a function that calls itself, but it does implement a recursion. " I how to convert my code block to recursive function. Can you help me, please?

x=[];

x(1)=1.8;

tol=0.01;

hata=tol+1;

n=1;

itr=0;

while hata>tol

x(n+1)=0.2*(4*x(n)+(32/power(x(n),4)));

hata=abs(x(n+1)-x(n));

n=n+1;

itr=itr+1;

end

I tried but i don't know how to do recursive function for this. You know recursive function should contain your function.

function [itr] = newton(x,tol)

hata=tol+1;

n=1;

itr=0;

while hata>tol

x(n+1)=0.2*(4*x(n)+(32/power(x(n),4)));

hata=abs(x(n+1)-x(n));

n=n+1;

itr=itr+1;

end

I'm trying to implement this algorithm:

my function

values of function

I would appreciate if anyone can help.

The Newton_Raphson is a recurrence formula, not a recursive one, so what you have written is correct. Look at the last value of x to see the solution.

Sir, could you help me when you are available?
