Hi all,

I am trying to use some of the stl's algorithm on eigen' data structure. However the stl's algorithm are iterator based, so quickly skim through the docs and I do not see much information about iterator (especially on matrices).

is eigen's data structure compatible with stl's algorithm?

We don't provide our own STL iterators interfact yet with begin()/end(), but eigen vectors/matrices are stored sequentially in memory, no padding/spacing, so they're very easy to address by pointers, and STL algorithms accept that.
