How to extract all the values from a while loop into a vector

I have the following function

function c = nice(n)

c = n

while c ~= 1

if rem(c,2) == 0
    c = c/2
else c = 3*c+1

end

end

and I am trying to insert all the c values into one vector. Any hints on how can I do it?

AC, use something like

 function c = nice(n)
 ii    = 1;
 c(ii) = n;
 while c(ii) ~= 1
    ii = ii + 1;
    if rem(c(ii-1),2) == 0
        c(ii) = c(ii-1)/2;
    else
        c(ii) = 3*c(ii-1) + 1;
    end
 end
 end

function c = nice(n)

c = n;
jj = 0;
while c(end) ~= 1
    if rem(c(end),2) == 0
        h = c(end)/2;
    else 
        h = 3*c(end)+1;
    end
    c = [c;h];
    jj = jj + 1;
    if jj >= 30, break; end
end
