I considered adding a routine for pretty-printing but I realised there
are many possible formats that people would want (GNUPlot, Fortran,
R/S, Octave/Matlab, Maxima, LaTex, HTML, GP-PARI, XML, etc) and that I
I couldn't write one that was sufficiently general to handle all the
possibilities. In particular there are also several common ways of
displaying complex numbers X Y, (X,Y), X+Y*I, X+Y*J.
I wanted to avoid the trap of adding "just one more" format each time,
or creating a function with so many arguments that it was difficult to
use, so I left it alone.
If I'm feeling strong I will think about it again.
