How to store the data of specific loop values?

Hi,

I have a loop 1:100 and I want to store the output of i = 1,6,11,....

How should I code this?

Thx

Did you read the Matlab Onramp already?

result = zeros(1, 100);   % Pre-allocation
for k = 1:100
    result(k) = rand;     % your value
end

Or maybe you mean:

index  = 1:6:100;
result = zeros(1, numel(index));   % Pre-allocation
for k = 1:100
    match = (k == index); 
    if any(match)
        result(match) = rand;      % "logical indexing"
    end
end

@Jan I guess the second part does what I want. Thanks!
