peicewise(x<2,{1,2,3}*X,SIN(-{1,2}))

Things like that can really throw the graphing engine for a loop and it is unclear exactly how best to handle it. Once we figure out how to do so the rest is pretty easy since automatic list processing already exists.


How about simply require that all lists be the same length? Basically, do what is done in Home by generating an error message whenever they are not the same length. (Please, not like what is done in CAS where missing elements are sometimes treated as zero, {1,2,3}+{3,4}={4,6,3}, and sometimes ignored, {1,2,3}*{3,4}={3,8}.)

This would be a really useful feature. I have a student using the Prime who recently asked about this as it is available on the TI calcs.
