Hi, Florent. The scoring in Cody is based on the number of nodes in the parse tree, and strings only require one node. You can have a look for yourself by typing: '>> mtree('back_and_forth.m','-file').show'. Try to do it for the same code, without str2num, and you'll see that even small things like parenthesis or plus signs require their own node in the tree. In terms of performance, the two versions are not so different. The problem here is that every solution, that use str2num in this way, will have the same Cody score, regardless of how elegant or efficient the anonymous function is.

That would be something, wouldn't it? The mistake was copy-pasting this version, with the [1 1]s, instead of a version without them. They are not needed, as you noticed.

Hi, Heather. To be honest, this was an older version that I was using to test containers.Map, and ended up submitting by mistake.

Sorry for the nasty solution. I'm hoping the use of str2num and anonymous functions will eventually be limited, since most simple problems can be solved with this cheat.
