Question

A Fibonacci sequence is composed of elements created by adding the two previous

elements. The simplest Fibonacci sequence starts with 1,1 and proceed

s as follows:

1, 1, 2, 3, 5, 8, 13, ...

However, a Fibonacci sequence can be created with any two starting numbers.

Create a MATLAB function that creates a Fibonacci sequence. There should be

three

inputs. The first and second number

of

the

desired

Fibona

cci sequence and the total

number of elements desired for the Fibonacci sequence.

For example, if you use your completed function to solve for the Fibonacci sequence

where the first two numbers are 3 & 4 and your total number of elements is 5, your

functi

on should return:

[3, 4, 7, 11, 18]

Explanation / Answer

function fib = fibonaci(a,b,n)
%empty array
fib = [];
%while n is greater than zero
while(n>0)
% add element to fib array
fib = [fib a];
%update elements
temp = a;
a = b;
b = b+temp;
%reduce n
n = n-1;
end
end
%call function
disp(fibonaci(3,4,5));

% sample output
% 3 4 7 11 18
