[edit] Summary

Description

Plot of the modified Bessel functions of 2nd kind K0(x) in red, K1(x) in green and K2(x) in blue. The plot was produced running Gnuplot on the following code:

set terminal svg
set output "BesselK_plot.svg"
set title "Modified Bessel function of second kind"
set xlabel "x"
set ylabel "K_n(x)"
set xrange [0:4]
set yrange [0:4]
set xzeroaxis linetype -1 linewidth 0.5
set yzeroaxis linetype -1 linewidth 0.5
set xtics axis
set ytics axis
plot "besselk.dat" using 1:2 title "K_0(x)" with lines linewidth 2, \
     "besselk.dat" using 1:3 title "K_1(x)" with lines linewidth 2, \
     "besselk.dat" using 1:4 title "K_2(x)" with lines linewidth 2

the file "besselk.dat" contains the values of the Bessel functions and can be produced with the following Matlab commands:

t=0:0.001:4;
K = [t; besselk(0,t); besselk(1,t); besselk(2,t)];
K = K';
save -ascii "besselk.dat" K;

It was then post-processed with Sodipodi.
