How do I print my data to a .txt file?

Haven't been able to make sense of the info on MathWorks. All I'm trying to do is write the outputted vector from my function to a text file.

Here's what I've tried

fileID=fopen('solution.txt');
fprintf(fileID,'%e',x);

x is the outputted 1x5 or 1x10 vector. Just want to put it into a text. Any help on what I'm doing wrong?

Note that if all you want to do is write a single array to a text file and close the file, then dlmwrite is much simpler:

dlmwrite('solution.txt', x); %that's all, although you can go fancier if you want

according to the fopen documentation you need to supply the second option permission to tell it that you want to write to the file:

fid = fopen(filename,'wt');

You should probably use the text option too, as I have shown in my example above.
