Hello,

You can avoid its error by a following way.
But I don't know why the way doesn't cause error.

$\psmatrix[colsep=7em,rowsep=2.8ex,mcol=l] & \left( \frac{1}{5}\right)^r & r=-1.4306\dots\\ & \left( \frac{3}{4}\right)^s & s=-8.0039\dots\\ & 2^t & t=3.3219\dots\\ & \eu^u & u=2.3025\dots\\[0cm] %<------ add [0cm] [mnode=circle] 10 & \pi^v & v=2.0114\dots\\ & 5^w & w=1.4306\dots\\ & 10^x & x=1\\ & 25^y & y=0.7153\dots\\ & 100^z & z= 0.5\\ \endpsmatrix$

Thanks,
Atsushi Tanabe

I am having difficulty changing the node style at the beginning of a
row of a matrix. See the following:

%-------- This works:

\documentclass[11pt]{article}
\listfiles

\pagestyle{empty}

\usepackage{pstricks}
\usepackage{pst-node}
\usepackage{multido}

\newcommand*{\eu}{\ensuremath{\textnormal{e}}}

\begin{document}
$\psmatrix[colsep=7em,rowsep=2.8ex,mcol=l] & \left( \frac{1}{5}\right)^r & r=-1.4306\dots\\ & \left( \frac{3}{4}\right)^s & s=-8.0039\dots\\ & 2^t & t=3.3219\dots\\ & \eu^u & u=2.3025\dots\\ 10 & [mnode=circle] \pi^v & v=2.0114\dots\\ <--- changing this node works OK & 5^w & w=1.4306\dots\\ & 10^x & x=1\\ & 25^y & y=0.7153\dots\\ & 100^z & z= 0.5\\ \endpsmatrix$
\psset{nodesep=3pt,arrows=->}
\multido{\ia=1+1}{10}{
\ncline{5,1}{\ia,2}
\ncline{\ia,2}{\ia,3}
}
\end{document}

%------------------  This doesn't work---see message below:

\documentclass[11pt]{article}

\psset{nodesep=3pt,arrows=->}
\multido{\ia=1+1}{10}{
\ncline{5,1}{\ia,2}
\ncline{\ia,2}{\ia,3}
}
\end{document}
