How can I print something like this: fprintf(fileID,'>|/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/|< \r\n'); or like fprintf(fileID,'\\');
I get: Control Character '\/' is not valid. Thanks

str = '>|/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/|<';
fprintf(fileID, '%s\r\n', str);
fprintf(fileID, '\\\\')

\ starts many escape characters, like \n or \r. To print a single \, you have to use the escape character \\.
fprintf(fileID, '>|/\\/\\/\\/\\/\\/\\/\\/\\/\\/\\/\\/\\/\\/\\/\\/\\/\\/\\/|< \r\n');
fprintf(fileID, '\\\\')
Note that you can print to fileID 1, which is the standard display. This is quite useful for testing.
fprintf(1, '%%\\')
