Hi,
I do not know the file name at the time of coding. As I get data, it will be stored as "user.txt" Now I need to fill in my code the path and the filename once. Now I shall read the file, process it and save many output files as "useroutput.txt", "useroutput.jpg", and so on. in the same path as the data file. I don't want to keep editing each and every place and time.
How can I do this? Any help is appreciated. Thank you for your time.

for i = 1:10
txtFile = strcat('user_',num2str(i),'.txt') ;
imageFile = ['userImage_',num2str(i),'.jpeg'] ;
% save using the file names
end

Thank you KSSV,
I have something in my mind like this...
FileId: %enter your filename
PathId: %enter your path to the file
Textread('pathId/fileId',%f')
...
fopen('pathId/fileId+output.txt','w')
...
exportgraphics('pathId/fileId+output.jpg')
Is it possible to this in matlab?
