I'm trying to compute f(x0), f(f(x0)) (written as (f 3 )(x0)), and (f 100)(x0). With the given initial value x0 ∈ [0, 1]. But i'm not sure where I'm getting the error

let x0=0.35 and y=f(x0)

calculting f^N(x0) N can be 1,2,3, or 100

Let N=100;
x₀=0.35;
fN=f(x0);
For i = 1: N-1
End
fN

This is not Matlab. There is neither a "Let" command, nor a "For". x₀ is not a valid name of a variable.

Please read the Getting Started chapters and look an Matlab's Onramp to learn the basics.

N  = 100;
x0 = 0.35;
y  = f(x0);
for k = 1:N-1
  y = f(y);
end
y

Thankyou! I definilty need a refresher
