Question

Matlab help?! Write a matlab code to prove (or disprove) the Collatz Conjecture. Run the code for a few different values of n, and make note of the results. Did n always eventually go to 1?

Tips: You will need to use a while loop. While your integer, n, is greater than 1, you want to continue doing the calculation (i.e. n/2 if even and 3n+1 if odd). Once n reaches 1 (or something less?), you want the program to end.

Within the while loop, an if statement is necessary to determine which calculation you should do, depending on if n is even or odd at the time( by using the mod function).

Answer 1

while (n> 1)
if (mod(n,2)) % this is odd if 1 (true)
disp('ODD');
else
disp('EVEN');
end;
end; % while n>1

disp('n less than or equal to 1');

Answer 2

is this what you want ?

n=5
while (n> 1)
if (mod(n,2)) % this is odd
%disp('ODD');
n= 3*n+1
else
%disp('EVEN');
n= n/2
end
end; % while n>1
