I'm happy with a two-step method:

  Step 1: Save data to text file.

    tmp = [x', y'];
    save -text 'main.dat' tmp

  Step 2: Use Gnuplot to plot `main.dat'

    set term pslatex color solid rotate 8
    set ylabel 'Bit error rate'
    set xlabel '[t] {Average bit energy-to-noise density ratio, \
                     $\gamma$ (dB)}'
    set output "plot.tex"
    plot [ : ] [ : ] "main.dat" not w l lt 1 lw 1

In the LaTeX source, do a `\input {plot}'.

  plot (x, y, ';;')
