Output of a for loop into a vector?

I need to get the output of this for loop that I created

x=[1 8 3 9 0 1];
b=0;
for i=1:length(x)
  b=b+x(i);
end

to put the answers b into a vector eg y=[1 9 12 21 21 22]

I cant seem to do it, i feel like i need to add a y=zeros(size(x)) or something similar but nothing seems to work

thanks

You could simply use,

 b = cumsum(x)

but if you must use a loop then,

x=[1 8 3 9 0 1];
b=zeros(size(x));
for k=1:numel(x)
  b(k)=sum(x(1:k));
end
