How do I export the information contained in the psd output so that I can plot the data and frequencies using a non-MATLAB program such as gnuplot

Assuming you are using the newish version of psd objects ...
Starting with the example from spectrum:
Fs = 1000;
t = 0:1/Fs:.296;
x = cos(2*pi*t*200)+randn(size(t));
h = spectrum.welch;
Hpsd = psd(h,x,'Fs',Fs);
Then you could simply do:
csvwrite('filename.txt', [Hpsd.Frequencies, Hpsd.Data])
