The code I have is where f is a function handle, a is a real number, and n is a positive integer:

function r=mynewton(f,a,n)
syms x
f=@x;
c=f(x);
y(1)=a;
for i=[1:length(n)]
y(i+1)=y(i)-(c(i)/diff(c(i)));
end;
r=y

The erros I am getting are:

Undefined function or variable ‘x’.
Error in mynewton (line 4)
c=f(x);
