octave source code

The .svg version of the file, along with a better quality encapsulated postscript file, is produced by

  • the following octave source code,
  • in a local directory called /tmp
## octave script 
## * output files created in /tmp : tanh.(eps|svg)
## * the .svg file is likely to have font problems, the .eps file should be OK
set(gcf(),"defaultlinelinewidth",3);
phi=linspace(-5,5,500);
plot(phi,tanh(phi),'-',
     [-5 5],[-1 -1],'-k','linewidth',1,
     [-5 5],[1 1],'-k','linewidth',1)
set(gca(),"fontsize",24, "linewidth",3);
xlabel('{\fontsize{32}\phi}');
ylabel('{\fontsize{32}\beta = tanh \phi }');
axis([-5 5 -1.5 1.5])
