EDIT: released again to fix a typo in set_DoesNotContains(2); now it is set_DoesNotContain(2)

Hi Davide. Thanks. It is a genial plugin. This attempt remains for history. Would it be too much to ask to add functions like choose and permute? And an option to return the sets as row vectors or column vectors by default?

A small example on how to calculate probabilities with a dice thanks to the plugin.

Hi Davide. Thanks. It is a genial plugin.

You're welcome, I'm very glad this project is useful to the community. It started out for fun, to play around with matrices and SVG features in the API, but it quickly developed into something more coherent and articulated.

Totally forgot about this gem.

I think is feasible, set_PowerSet() already has a n choose k algorithm, it just need to be adapted.

This is something already partially implemented, I need to finalize it.

Very nice.

I can say your example file for set plugin works with mono.

Thanks to this plugin it looks that SMath is ready to be used in a finite mathematics course.
