Talk:Element-wise operations

Can we cut back on the matrix fetish? If you need it for serious work, go get a good quality matrix library for your language. Implementing your own matrix class is always a bad idea. The task could have said "vector", which is a lot simpler to write a short clean implementation for and much more to the point.

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? -- Ledrug 18:57, 9 June 2011 (UTC)
