Run with lualatex or latex->dvips->ps2pdf

The initial values für y(-10) and y'(-10) are guessed and not really 
calculated

\documentclass[border=5mm]{standalone}
\usepackage{pstricks-add}
\begin{document}

\def\Funct{ exch x mul}%   y'' = y*x         on stack y y''
\psset{xunit=1.5, yunit=5, method=varrkiv, showpoints=true}
\begin{pspicture}(-11,-1)(1,1.1)
\psaxes[Dy=0.2]{->}(0,0)(-11,-1)(1,1)
\psplotDiffEqn[varsteptol=.00001,plotpoints=500, 
linecolor=red]{-10}{0}{0.05 1}{ \Funct }
\psplotDiffEqn[varsteptol=.00001,plotpoints=500, 
linecolor=blue]{-10}{0}{-0.35 0}{ \Funct }
\end{pspicture}

\end{document}

\psplotDiffEqn [Options] {x0}{x1}{y0}{ f(x,y,y’,...) }
