Pulling values from vectors
显示 更早的评论
I have two fairly basic questions about pulling values from vectors.
n=0:40;
i=n+1
income(i) = initial_income*(1+inflation).^(n)
income(1)
My goal is to pull the second vector from the list while using 1 as the indicator. I'm working in terms of years and income(1) doesn't justify the first year. It amounts to the initial value. I need income(1) to be what currently is income(2) and income(2) to be income(3) so on so forth. How can I manage to do this?
Here's my second question. I know income(1) pulls the first value, but what does income(i) imply? I'm under the assumption that it needs to be used here, but I also want to make sure I understand the reasons why I would use it.
Let me know if anymore information is needed. Thanks!

Nope. It doesn't:
income = initial_income*(1+inflation).^(1:40);

You mean you want to start with a vector income and then have the values stored in the vector shift locations? There are a number of different ways to do that, depening on what you intend for the final value:
income=randi(100,1,5) %example
incomeShifted=income(2:end) %truncated shift
incomeShifted=circshift(income,-1) %circulant shift
incomeShifted=[income(2:end) , 0] %padded shift
