display while loop output as an array

how do you display the output of a while loop as an array.

code:

function [] = hailstone_sequence(n)
n = input('Value for n: ');
h = 1;
while(n~=1)
if n==1
return
elseif mod(n,2)
        n=3*n +1
else
n=n/2
end
h=h+1;
end

what's your output variable ?

[Ahmed Emam]

the output should be the values for each iteration in an array, so for 3 the output should be 3 10 5 16 8 4 2 1

Answer 1

[Walter Roberson]

Just before the h=h+1 insert

output(h) = n;

[Ahmed Emam]

tried it, works but I am missing the initial value

[Walter Roberson]

Then move it to after the while() statement.

But question: does the output need to include the 1? If so then make sure to add a 1 to the end before the return statement.

Answer 2

[jean claude]

function [output] = hailstone_sequence(n)
output=[n];

h = 1;
while(n~=1)
if n==1
return
elseif mod(n,2)
        n=3*n +1
else
n=n/2
end
h=h+1;
output= [output n];
end
