3[20%] | Fibonacci numbers are the numbers in a sequence in which the first two ele- ments are 0 and 1, and the value of each subsequent element is the sum of the previous two elements: 0,,,2,3, 5, 8, 13, Write a MATLAB program in a script file that determines and displays the first 20 Fibonacci numbers.

Answer 1

n = 20; %20 terms
fib = zeros(1, n);
fib(2) = 1;
for i = 3:n
fib(i) = fib(i-1) + fib(i-2);
end
fib

output

=====

fib =
