Saving signal as a text file

Hi. I am having problems saving a signal as a text file. Let's assume we have the signal below, how can I save xt as a text file with the first column representing the time the second column representing the amplitude?
Fs = 8000; % samples per second
Ts = 1/Fs; % seconds per sample
t = 0: Ts: 3; % Start signals at 0sec and stop after 3sec
% Sine wave x1[n]:
Fc = 1;
x1 = sin(2*pi*Fc*t);
% Sine wave x2[n]:
Fc = 760;
x2 = sin(2*pi*Fc*t);
% Sine wave x3[n]:
Fc = 1280;
x3 = sin(2*pi*Fc*t);
% Sine wave x4[n]:
Fc = 2000;
x4 = sin(2*pi*Fc*t);
xt = x1 + x2 + x3 + x4;

How about making it a csv file:
filename = 'deleteme.csv' % Whatever you want.
csvwrite(filename, [t', xt']);
type(filename) % type to command window.
%delete(filename); % Delete the file.

If you want no header and a space between the numbers, use this:
filename = 'deleteme.csv' % Whatever you want.
dlmwrite(filename, [t', xt'], 'delimiter', ' ');
type(filename) % type to command window.
