create a new file

??? Error using ==> feof Invalid file identifier. Use fopen to generate a valid file identifier.

fid =

     3

What went wrong and I also wonder if the three answers equal 23 after creating the text means that anything is wrong?

Answer 1

[Walter Roberson]

The routine name is fgetl ending with a lower-case L, not fget1 ending with the digit One.

The 23 just means that fprintf() wrote 23 characters to the file.

Answer 2

[garima chandel]

??? Undefined function or method 'fgetline' for input arguments of type 'double'.

Error in ==> fgetl at 23 y = fgetline(fid);

Error in ==> eeg_getversion at 40 fgetl(fid);

Error in ==> eeglab>eeg_mainfig at 1202 W_MAIN = figure('Units','points', ...

Error in ==> eeglab at 449 javaobj = eeg_mainfig(onearg);

Getting error while loading eeglab command. Please help.
