I'm trying to create a GUI that will ask the user for a folder path and do some calculations based on it.
There's anywhere between 1-15 files per folder.
I'm stuck at printing the table output and having matlab ignore any temporary files that starts with ~\$
filePattern = fullfile(myFolder, '*.xlsx');
theFiles = dir(filePattern);
for k=1: length(theFiles)
baseFileName= theFiles(k).name;
fullFileName=fullfile(myFolder, baseFileName);
Day{k}=extractBetween(fullFileName,"Day","_");
TotalTemp{k}= sum(data1{k});
TotalCost{k}= mean(data2{k});
T=table(Day, TotalTemp, TotalCost)
end

I was able to update the code to skip the tempoary files.
filelist = dir;
filelist = filelist(~startsWith({filelist.name}, '~\$''));
I'm still having trouble getting it to loop and print out the correct output.
for k=1: length(theFiles)
baseFileName= theFiles(k).name;
fullFileName=fullfile(myFolder, baseFileName);
day{k}=extractBetween(fullFileName,"Day","_");
data1{k}=rmmissing(data1{k});
total1{k}= sum(data1{k});
data2{k}=rmmissing(data2{k});
total2{k}= mean(data2{k});
total3{k}=total1{k}*total2{k}-20;
T=table(day, total1, total2, total3);
end

theFiles(k) is the struct with the directory entry. You should be passing in the file name, which you stored in fullFileName
