Mario,
Thanks a lot for posting the examples. For each one a picture
is rendered but I also get this message:
gnuplot> splot '/home/robert/maxout.gnuplot_pipes' index 0 t '' w l lt
1 lc rgb 'green'
^
line 0: ';' expected
The Gnuplot version is gnuplot 4.0 patchlevel 0.
About cabs, it is not a simplifying operator (although I'm pretty
sure we have raised the idea of making it simplify).
float(abs(gamma(5+%i*7))) returns a noun, %CABS, so it
is not evaluated to a number.
float(abs(gamma(5+%i*7))), nouns;
does return a number. In the past I've considered putting code
into into COERCE-FLOAT-FUN to cause nouns to be evaluated.
That would help this particular problem and also prevent the same
problem with other nouns that happen to be generated.
All the best
Robert
