Hi all,
I need to define numerical coefficients (essentially at random) and then use
them with commands, say like \CoeffAlpha, \CoeffBeta, and so on.
More precisely, how can I define the command \RandomCoeff, so that
\RandomCoeff{Beta}{1}{10} yields a command named \CoeffBeta, which is a random
number chosen between 1 and 10?
I tried to use the following approach, but could not make it work:
%%% begin random-coeff.tex
\setuprandomize[2012] % set a seed
\ctxlua{CoeffAlpha = math.random(1,10) ;}
\def\CoeffAlpha{\ctxlua{tex.print(CoeffAlpha)}}
%%%%%
\define[3]\RandomCoeff{%
\ctxlua{a = math.random(#2,#3)}
% \csname{Coeff#1}\endcsname{\ctxlua{tex.print(a)}} %% this line does not
work as expected...
}
\starttext
\CoeffAlpha
\RandomCoeff{Beta}{1}{10}
\ctxlua{tex.print(a)}
%\CoeffBeta
\stoptext
%%% end random-coeff.tex
Thanks in advance for any suggestion or hint.
Best regards: OK
