How can I export a waveform plot to .csv or .wfm?

I am trying to generate and combine two arbitrary waveforms with some added amount of random noise, then export that to a file which will be used in my Labview vi.

Is there a way to export the waveform to a .csv or .wfm?

Example code

%Set parameters
timeStep = 0.001;
time = 0:timeStep:(1-timeStep);
amplitude1 = 0.4;
frequency1 = 8;
amplitude2 = 0.7;
frequency2 = 14;
waveform1 = amplitude1*sin(2*pi*frequency1*time);
waveform2 = amplitude2*sin(2*pi*frequency2*time);
%Add waveform1 + waveform2
waveform = waveform1 + waveform2 
%Add noise
waveform = waveform + 0.3*rand(1,size(waveform,2));
waveformArray = (waveform./max(waveform))';
plot(waveformArray);
xlabel('Samples');
ylabel('Amplitude');
