And the task with the Lisp example is lousy. Do you check if the dimensions match? Can you even tell if the object is indeed a matrix? If the dimensions are wrong, does it just blow up or silently give some undefined answer? -- [[User:Ledrug|Ledrug]] 18:57, 9 June 2011 (UTC)
:It may be fine for educational purposes as long as we add a disclaimer saying that this is probably not the best way to do things in most languages (although we already have a disclaimer [[Rosetta_Code:General_disclaimer|here]] that says code here shouldn't be used for so called "serious work"). This task is probably pretty much perfect for array programming languages like [[APL]] and [[J]]. --[[User:Mwn3d|Mwn3d]] 20:54, 9 June 2011 (UTC)
::I'm not worried about someone mistakenly using any code for mission critical job, but rather that choosing matrix as the subject here is suboptimal. The task basically wants to demonstrate operator overloading, and using a 1-D vector is good enough to show it--in fact better, because there would be less cruft involved. It's also questionable if it illustrates anything for a real matrix-oriented environment: in Matlab, you do element-wise multiplication between matrices by "a = b .* c", which is rather boring. And how is this task really unique from all the other existing matrix-related tasks on this site? --[[User:Ledrug|Ledrug]] 21:52, 9 June 2011 (UTC)
