I'm trying to generate 31 excel files with a for loop:
days=31;
for i = 1:1:days
dataday = frequency(1,((i-1)*(size(frequency,2)/days)+1):(size(frequency,2)/days)*i);
xlswrite('frequency.xlsx',dataday');
end
Why I can not obtain 31 Excel files? Thanks in Advance!

If you wish to create a new Excel file for every iteration of the loop, you can use:
xlswrite(strcat('frequency',num2str(i)),dataday');
The term 'frequency' is concatenated with the iteration number.
The data for every iteration will be written to the first sheet of every file. The files will be saved in the current directory and will be named:
'frequency1.xls','frequency2.xls' ... 'frequency31.xls'

I believe you can add "i" to xlswrite('frequency.xlsx',dataday') like xlswrite('frequency.xlsx',dataday',i) to change the excel sheet everytime, so at the end you will end up with one excel file and in each sheet you have your data

Do you mean a text file? You can apply the same logic but obviously can't use xlswrite as you are not working with an Excel spreadsheet. What's the format of your data?
