Hi guys,
I'm learning the language while implementing an advanced package for
geometric and solid modeling.
My question is: What is the right idiom (shorter and/or faster) for writing
this kind of array indexing:
linesFromLineArray(V,EV) = Any[[V[:,EV[:,k][1]] V[:,EV[:,k][2]] ] for
k=1:size(EV,2)]
The efficiency is the strongest issue, since this method should provide the
indirect indexing for any kind of cellular complexes.
Many thanks for your help
