I've written some glue functions along the lines of what's in MLab.py: find unique union intersect setdiff setxor Quick questions: * any opinions on the algorithms used? * are these worth adding to MLab.py? If so, do I need to provide documentation updates? I can send this as a patch to MLab.py too. * Does anyone have opinions on what to do about the optional outputs from matlab functions? Is it worth trying to provide index matrices as second arguments, for example? If so, any opinions on implementation? a matlab user trying to get started with Numeric, Mark
