Rot4 and Iso4 had to be left out, since Rot4 apparently lacks a working
constructor.
Thereby (almost) all types in nalgebra can now be used for quickcheck-style
testing.
"arbitrary" is now a conditionally compiled feature that contains these impls
adding a dependency on quickcheck.
This is just a quick-fix so that nalgebra compiles.
This does not fix the deprecation warnings!
Version of rustc: 0.13.0-nightly (d91a015ab 2014-11-14 23:37:27 +0000).
Version of rustc: 0.11.0-pre-nightly (faa7ba7 2014-05-31 01:06:40 -0700).
Main changes:
* `cmp::Ord` -> `cmp::PartialOrd`
* `cmp::Eq` -> `cmp::PartialEq`
Note that `na::PartialOrd` is not the same as `cmp::PartialOrd`
(which lacks a lot of partial ordering operators).
This allows the implementation of householder reflection without relying
on knowledge of DVec. This required a new member in the Indexable trait:
the shape() function, which returns the maximum index available.
Version of rustc: 0.10-pre (b0ce960 2014-02-17 22:16:51 -0800)
This replaces uses of the `Orderable` trait by a `PartialOrd` trait: the `min` and `max` methods
are replaced by `inf` and `sup` methods.
Vectors do not implement the `Ord` trait any more.
Fix#4
This is to make people prefer the functional style.
Things like `a.dot(b)` dont make sense per se (there is no reason for `a` to have a different
status than `b`). Using static methods avoid this.
In-place methods are left unchanged.
Before, it was too easy to use an out of place method instead of the inplace one since they name
were pretty mutch the same. This kind of confusion may lead to silly bugs very hard to understand.
Thus the following changes have been made when a method is available both inplace and out-of-place:
* inplace version keep a short name.
* out-of-place version are suffixed by `_cpy` (meaning `copy`), and are static methods.
Methods applying transformations (rotation, translation or general transform) are now prefixed by
`append`, and a `prepend` version is available too.
Also, free functions doing in-place modifications dont really make sense. They have been removed.
Here are the naming changes:
* `invert` -> `inv`
* `inverted` -> `Inv::inv_cpy`
* `transpose` -> `transpose`
* `transposed` -> `Transpose::transpose_cpy`
* `transform_by` -> `append_transformation`
* `transformed` -> `Transform::append_transformation_cpy`
* `rotate_by` -> `apppend_rotation`
* `rotated` -> `Rotation::append_rotation_cpy`
* `translate_by` -> `apppend_translation`
* `translate` -> `Translation::append_translation_cpy`
* `normalized` -> `Norm::normalize_cpy`
* `rotated_wrt_point` -> `RotationWithTranslation::append_rotation_wrt_point_cpy`
* `rotated_wrt_center` -> `RotationWithTranslation::append_rotation_wrt_center_cpy`
Note that using those static methods is very verbose, and using in-place methods require an
explicit import of the related trait.
This is a way to convince the user to use free functions most of the time.
