Vectorize sum of discount rates
显示 更早的评论
Hi,
I want to vectorize the calculation of series like this: [R^0;R^0+R^1;R^0+R^1+R^2;...etc.
Im quite sure this should be easy, but i cant figure it out. Any help is greatly appreciated! :-)

R = 5;
cumsum(R.^(0:4))

out=1/(1-R).*(1-R.^(1:n));

R = 23;
n = 100;
x = repmat(R, 1, n);
x(1) = 1;
Result = cumsum(cumprod(x));
