2020-09-28Redefine itv_bound with BRight_if and BRInfty_ifKazuhiko Sakaguchi
2020-09-28The new interval libraryKazuhiko Sakaguchi
- `x <= y ?< if c` (lersif) has been replaced with `x < y ?<= if c'` (lteif) where `c'` is negation of `c`. This change makes statements of several lemmas (e.g., `lteif_orb`) easily comprehensible. - The first constructor `BOpen_if` of `itv_bound` has been replaced with `BClose_if` where the first argument is inverted. Now `pred_of_itv` is defined by using `lteif` instead of `lersif`. - Intervals of `T : porderType` form a `porderType` where the ordering relation is the subset relation. If `T` is a `latticeType`, intervals also form a `latticeType` where the join and meet are intersection and convex hull respectively. They are distributive if `T` is an `orderType`.

Putting `ord1` in `fintype.v`

2020-09-27Putting ord1 in fintypeCyril Cohen
ord1 is in zmodp, but it does not really require the zmodType structure of 'I_n to be stated and proven if we state it with ord0. We still keep the variant in zmodp with 0 instead of ord0 (for readability purposes).

2020-08-13Be robust to a change in the default argument naming algorithm.Jasper Hugunin
Overlay for coq/coq#12756, which changes the default argument name to just `S` from `S0`. This change preserves the old name; switching instead to use `S` may be preferable but introduces a potential impact on downstream users of mathcomp.
2020-08-12Get rid of displays in class fields and mixin parametersKazuhiko Sakaguchi
- In the definition of structures in order.v, displays are removed from parameters of mixins and fields of classes internally and now only appear in parameters of structures. Consequently, each mixin is now parameterized by a class rather than a structure, and the corresponding factory parameterized by a structure is provided to replace the use of the mixin. These factories have the same names as in the mixins before this change except that `bLatticeMixin` and `tbLatticeMixin` have been renamed to `bottomMixin` and `topMixin` respectively. - Added a factory `distrLatticePOrderMixin` in order.v to build a `distrLatticeType` from a `porderType`.
