I have a script that generates some data and outputs it to a text file. I want to modify it so it allows the user to save directly to whatever folder they want to save it in, rather than just have it save in the folder with the script. Here is the section that generates the .txt file.
T = [x,y];
fileID = fopen('output_data.txt','w');
fprintf(fileID,'%6s %12s\n','x','y');
fprintf(fileID,'%6.2f %12.8f\n',T);
fclose(fileID);

You can use uigetdir to open a dialog and allow the user to browse for the folder in which to save the file. Read the documentation (which includes examples) here: uigetdir
Then you would modify your fopen call to specify that the file will be in the selected folder. So, something like this:
outputPath = uigetdir
fileID = fopen(fullfile(outputPath, 'output_data.txt'), 'w');
