Fibonacci numbers are the numbers in a sequence in which the first two elements are 0 and 1, and the value of each subsequent element is the sum of the previous two elements: 0, 1, 1, 2, 3, 5, 8, 13, ...
Write a MATLAB program in a script file using a for-loop that determines and displays the first 20 Fibonacci numbers.
Hint: Initialize the first and second elements to be 0 and 1, respectively, and calculate those elements from the third element on.
