Ran in:
Initial = 200; % initial investment
D = [

10 151.39];
r = 0.01:0.01:0.05; % discount rate
for k = 1:size(D,1)
PVDCF(k,:) = D(k,2)./(1+r).^D(k,1);
end
PVDCF
PVDCF = 10×5

PV = sum(PVDCF) % sum present value for each discount rate
PV = 1×5
734.4060 691.3247 651.8614 615.6644 582.4196
NPV = sum(PVDCF) - Initial % NPV for each discount rate
NPV = 1×5
