hi all,
I have an array of 365 values and I do some calculations with an index for k=1:365
However, I need to do some different calculations for some k (let's say k=7, k=9,k=11, k=12)
how can I select only these?
I imagine is something like that: for k=1:365
if k=7.....
else...
thanks

It is easiest to address them directly:
v = randn(1,365); % Create Data
k = 1:365; % Index Vector
select_k = [7 9 11 12]; % Select ‘k’ Values
select_v = v(select_k); % Select ‘v’ Values

My pleasure.
You are not a pain. If you have previous programming experience, learning MATLAB will be relatively easy, once you get used to the conventions and programming environment. If you have no programming experience, learning any programming language for the first time will be a challenge.
Learning MATLAB will be much easier if you use the online tutorials. Begin with Getting Started.
