How to output as a vector

ive got a coin toss simulation game where score is kept.

function = coin_toss(s(0),N)
%  coin toss simulation
%  a coin is tossed n times, at each point a score is given +1 for heads
%  and -1 for tails.

N=input(10)

for k=1:N

rand_number=rand;

if random_number<0.5

random_number(k,1)=-1;

else

random_number(k,1)=1;

for i=1:N,

      s(0)=-1

      s(N)= s(N-1)+random_number

end

end

end

I basicly want to have an output of the scores after each flip divided by the flip number in a vector e.g

[(-1/1),(s(1)/2),(s(2),3)........ (s(N)/(N+1)] [-1,

Still going at it.

What's the meaning of N = input(10)? I am guessing that what you wanted to do is to pass N to a function. But, if so, why ask for its value again inside the function? And if you know the first value is always -1 you don't really need to pass it either.

If you want to return a vector

function your_result = coin_toss(N);

%Preallocating for your_result:
your_result = zeros(N,1);
%Perform your calculations
your_result(1) = -1;
for ii = 2:N
    %do your stuff
    your_result(ii) = %You might know how to do this since it has already been answered
end
%You might also know how to do the rest. Hint: cumsum()
