Using for loops in referencing

Hello everyone

I would like to create new datasets separately through a for loop.

for n=0:5:40
    netload'n'=Y-n.*Koutput
end
% the results should give me nine outputs which would be somethig like
netload0=Y-0.*Koutput
netload5=Y-5.*Koutput
"" + ...
    
""
netload40=Y-40.*Koutput

How can I execute that using a for loop?

Thank you.

You should never create numbered, or sequentially named, variables. Embedding any form of indexing in the variable name is always a bad design. See Tutorial: Why Variables Should Not Be Named Dynamically for more details.

You don't even need a loop to perform your calculation:

n = permute(0:5:40, [1, 3, 2]); %create a vector 0:5:40 in the 3rd dimension
netload = Y - n .* Koutput;     %create a 8760 x 42 x numel(n) matrix

netload(:, :, 1) corresponds to n = 0, netload(:, :, 2) corresponds to n = 5, etc.

Ok Sir, Thanks

Thanks for your response. However for Y and Koutput with size(8760,42) the code returns the error, matrix dimensions must agree. Do I need to predefine the variable netload before using the above lines. Secondly, what does the [3,2,1] represent?

I used cell arrays to solve this problems but it is such a long way to code. Thank you once again

a little typo, it should be:

n = permute(0:5:40, [1, 3, 2]);
netload = Y - n .* Koutput;

Thanks, Andrei. Fixed now.

Thank you so much. This works
