I use a code:

Session = daq.createSession('ni');
addAnalogOutputChannel(Session, 'Dev2', 0:1, 'Voltage');
Session.IsContinuous = true;
Session.Rate = 10000;
data(:, 1) = [linspace(-1, 5, 5000) linspace(5, -1, 5000)]';
data(:, 2) = [linspace(-1, 10, 5000) linspace(10, -1, 5000)]';
lh2 = addlistener(Session, 'DataRequired', @(src, event) src.queueOutputData(data));
queueOutputData(Session, data);
subplot(2, 2, 1);
plot(data(:, 1))
subplot(2, 2, 2);
plot(data(:, 2))
startBackground(Session);
