Hello everyone, how can I run a code for different files in a folder? i.e, Each file is a dataset and the idea is to run the code to generate results independently in a .PDF file in another different folder, thanks.

You can manage this using for loops, provided that your datafiles are named in an incremental manner. Example, you have 10 files named data1, data2, ... data10.

inputpath='C:\Documents\Example\';
for i=1:10
    
    data=genericreadfunction([inputpath,'data',num2str(i),'.txt']); 
    
    %dataanalysis here
    
    reportfunction(['Analysis report no.',num2str(i),'.pdf']);
end

Of course since I have no idea what format your data is in, I cant say which of the numerous generic read functions you should use, nor how you should write your reports, but I hope you get the general idea :)

As an alternative, you can also use

[Name,Path]=uigetfile({'*.txt*'},'Find data...','MultiSelect','on');
for i=1:10
    fullpath=fullfile(Path{i},Name{i});
    data=genericreadfunction(fullpath);
    %data analysis here
end

@Jakob B. Nielsen the results for each file are separated by ´tabs´, how is possible to put independentely every tab in one sheet inside the resulting .PDF file ? Thank you.
