[edit] Summary

Plot of the modified Error function. The plot was produced running Gnuplot on the following code:

set terminal svg
set output "Erf_plot.svg"
set title "Error Function"
set xlabel "x"
set ylabel "erf(x)"
set xrange [-2.5:2.5]
set yrange [-1.2:1.2]
set xzeroaxis linetype -1 linewidth 0.5
set yzeroaxis linetype -1 linewidth 0.5
set xtics axis
set ytics axis
set key off
plot "erf.dat" using 1:2 title "erf(x)" with lines linewidth 2

the file "erf.dat" contains the values of the erf function and can be produced with the following Matlab commands:

t=-2.5:0.01:2.5;
E = [ t; erf(t)];
E = E';
save -ascii "erf.dat" E;

I made this picture by myself.
