Yes, surely :

%%%% Beginning of octave script
%%  Demonstrating impossibility to write more than 2Go by a single file
%% Be care of space disk available (must be > 2 Go)
fd = fopen( "test.bin" , "wb" ) ;
for k = [ 1:300 ]
    fwrite( fd , randn(1024,1024) , "double");
end ;
fclose( fd ) ;

ls -lh

% 'double' on x86 platform is 8 octets big, so each randn(1024,1024)
% call gives a 8 Mo matrix size. So, 300 matrix is 300x8 = 2400 Mo, 
% which is larger than 2Go. Please try, and read the exact size of 
% 'test.bin' to check if your file is bigger than 2 Go.
