Error using fscanf
Invalid file identifier. Use fopen to generate a valid file identifier.
Error in eeg (line 5)

Can you attach the file in question? It's hard to do anything without that.

The file your are looking for is probably not there, or at least, not on the MATLAB path. See what fid is: if it is -1, then you haven't really opened the file, which would result in the error that you are observing:
fid = fopen('badfile.txt')
fscanf(fid, '%f')
To double check if the file is accessible by MATLAB, run:
exist('eeg.txt', 'file')
