Hi all,
I am trying this:
for i = 1:length(originalData)
['data_hz' '_' num2str(i)] = selectedData(x1:x2);
end
I want to split my original data into different file names, but the code does not allow me to use this structure on the left side of the "=". Any hint please?
Thank you very much :)

Maybe you want some thing like this:
someFolder = 'D:\whatever';
for k = 1 : length(originalData)
baseFileName = sprintf('data_hz_%d.dat', k);
fullFileName = fullfile(someFolder, baseFileName);
save(fullFileName, 'selectedData');
end

Thanks.... That's a good way to do but I do not want to save in each loop! It will create tens of files!

Dear Mehdi,
Perhaps you want to split your data into different variables and not files and to save all of them in a single file. One good way will be to use struct fields, another will be to use cell array.
For struct fields something like this can do the job
for i = 1:length(originalData)
currVar = strcat('data_hz_', num2str(i)); %a meaningful variable name for you
splitData.(currVar) = selectedData(x1:x2); %you can use index also like splitData.(currVar)(i,k)
end
you can re-structure however you want your variables also.
