How to access the 3rd element in a for loop?
显示 更早的评论
investment = 1000;
interestRate = 0.01;
months =[1:12];
for month = months
investment = investment * (1 + interestRate);
end
Displays:
investment = 1010
investment = 1020.1
investment = 1030.3
investment = 1040.6
investment = 1051.0
investment = 1061.5
investment = 1072.1
investment = 1082.9
investment = 1093.7
investment = 1104.6
investment = 1115.7
investment = 1126.8

You would have to evalc() an invocation of the for loop, and do text processing on the output.
We would recommend that you instead record the values as you go.
investment = 1000;
interestRate = 0.01;
months =[1:12];
for month = months
investment(month+1,1) = investment(month,1) * (1 + interestRate);
end
format long g
investment
The third output of the loop would then be investment(4) [because investment(1) is the initial value]

investment = zeros(13,1);
investment(1) = 1000;
interestRate = 0.01;
months =[1:12];
for month = months
investment(month+1) = investment(month) * (1 + interestRate);
end
investment(4)
