Dear Kazuhiko,

Thanks a lot to you and the MathComp team for these great news, the integration of the order library in MathComp will make our lives much easier.

Best,
Xavier

Dear Xavier,

I have good news for you and who interested in Cyril's order library.

I'm have almost finished to port the order library into MathComp and
reimplement the ssrnum structures (numDomainType, realDomainType,
etc.) on top of the order structures.
Currently, there is no standard implementation of "pointwise orders
over matrices/vectors" and I'm not sure if our implementation is
stable enough. However, it is easy to share the notion of order with
various kind of ordered sets (ssrnum structures, matrices, intervals,
etc.) and provide a latticeType instance of matrices. I hope it is
really useful for someone...

I'll be glad to answer any questions. More details can be found here:

Best regards,
Kazuhiko

I am currently working on an order library
https://github.com/Barbichu/finmap/blob/master/order.v
Warning: draft version, work in progress, outdated header

I hope to merge it with ssreflect one day.
Great, thanks for sharing this information. We would be glad to use it
once you consider that it is stable enough!

Best,
Xavier
