MATLAB: Help with error “Reference to a cleared variable n”

Question

im trying to make a series that gives me n terms of the fibonaci series, ive got it to work like the pure code but now its having troble once i put it into a funtion file

function x = fib(n)
close all 
clear all
x=create_array(1,n,1)
for i=1:n
   x(i+2)=x(i)+x(i+1)
end 
end 

its having trouble with the variable n, also im calling a function inside this function so idk if this messes it up somehow?

Answer 1

Putting

clear all

inside the function clears the variable n that you just sent into it. You don't need that line.
