I have for example these three vectors : [1 2 3 ], [4 5 6 ],[7 8 9]. I would like to get the result like this in the file txt:

1 2 3 4 5 6 7 8 9

(each vector in a line) I tryed this

fid= fopen('h.txt','w');
fprintf(fid,'%.5f',h0);
fclose(fid)

but i didn't get the result. Delimiter ' ' doesn't work with this command.

在 MATLAB Online 中打开

fprintf(fid,'%.5f ',h0);

should be enough. Note the space in the string.

So i don't have to open and close the file everytime i add a vector to the file ? because in my program i have a for loop, in every iteration i add a vector to the file.

You can open the file once before the loop, and close it after the loop.
