Mike Dilger 122c95f2b4 fix macro 2015-01-01 10:41:07 +13:00
Mike Dilger 4c1cfb03cf ApproxEq trait enhanced with ULPs method of specifying closeness: 
approx_eq_ulps() allows specification of epsilon as an integer number
  of Units in the Last Place (ULPs) difference between the two floating
  point values

  default approx_ulps() is set to 8.

  approx_eq() function continues to use epsilon method, although I
  recommend further commits and a migration towards the ULPs method.

Sébastien Crozet a92c681d01 Update to the last rust-nightly.

Fix #54.

Eduard Bopp 11a2b84ee0 Derive Copy wherever sensible 
Copy is now opt-in, see [1]. To keep the current library functionality it is
derived for all sensibly copyable types.

Eduard Bopp 223dc316ad Update to latest Rust 2014-12-10 15:09:38 +01:00
Eduard Bopp edaeab72ac Use object-oriented style for trait methods 
Wherever sensible the geometric traits now take `&self` arguments, so that
implementations can be invoked as instance methods instead of static methods.
This makes some idioms easier to express and generally allows for greater
flexibility as the restructured methods can still be invoked like static
methods.

Fixes #39.

Sébastien Crozet 3b44441ce9 Update to the last rust-nightly.

Sébastien Crozet d296bebfac Replace the double dispatch trick by multidispatch! 
Fix #38.
 2014-11-26 14:23:30 +01:00
Sébastien Crozet 3317e057f5 Add float constants to `BaseFloat`. 
Fix #42.
 2014-11-25 11:19:31 +01:00
Sébastien Crozet 40c14ace39 Make `from_array`-like methods static. 
Fix #45.
 2014-11-25 11:00:26 +01:00
Eduard Bopp 956c5cdecc Implement assertion macros for ApproxEq 
These macros yield readable error messages as test assertions for ApproxEq
types. They can be invoked as:

    assert_approx_eq!(a, b);
    assert_approx_eq_eps!(a, b, eps);

Fixes #40.
 2014-11-23 14:15:56 +01:00
Eduard Bopp 733219d728 Have ToHomogeneous use &self in method signature 
I find makes the syntax a bit lighter.
 2014-11-22 12:01:45 +01:00
Eduard Bopp 2f3b68bebb Fix erroneous Translate documentation 
Looks like it's been copied & pasted without adapting.
 2014-11-21 15:59:26 +01:00
Sébastien Crozet bab38ca6d5 Add conversion from/to arrays for matrices and vectors. 
Use `.as_array()`, `.as_array_mut()`, `.from_array_ref()`, `.from_array_mut()`.
Fix #33.

Sébastien Crozet d8dfedbf99 Update to the last rust-nightly. 
Version of rustc: 0.13.0-nightly (336349c93 2014-11-17 20:37:19 +0000).
 2014-11-19 12:11:32 +01:00
Sébastien Crozet 77348f668f Use our own traits instead of the deprecated ones. 
We might switch to bjz/num-rs eventually (#32), but in the mean time we just re-declare the
deprecrated traits in nalgebra.
 2014-11-16 14:42:18 +01:00
Sébastien Crozet 39b9d20717 Quick update to the last rust-nightly. 
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).
 2014-11-15 15:47:59 +01:00
Sébastien Crozet 226b115f1e Overload `DVec * DVec -> DVec` and `DVec / Dvec -> DVec`. 
Fix #31.

Sébastien Crozet 36d3e88cb0 Do not automatically impl Scalar{Mul,Div,Add,Sub}. 
This makes them implementable without using the double dispatch trick.
 2014-10-30 09:21:22 +01:00
Sébastien Crozet 93b184815f Always use `Cast<f64>` instead of `Cast<f32>`. 2014-10-30 09:21:22 +01:00
Sébastien Crozet 6b4b25acd4 Basis: add a method to compute the i-th element of the canonical basis. 2014-10-30 09:21:20 +01:00
Sébastien Crozet 171576e2a0 Move the `eigen_qr` function behind the `EigenQR` trait. 
This simplifies generic programming.
 2014-10-30 09:21:20 +01:00
Sébastien Crozet 27be1f0651 Add a `SquareMat` trait for square matrices. 2014-10-30 09:21:20 +01:00
Sébastien Crozet 6a194b2b62 Rename: Any{Vec,Pnt} to Num{Vec,Pnt} + do not impl them automatically. 
Instead, implement them manually. This clarifies error messages for the users.

Sébastien Crozet 628aac0961 Coding style fix. 2014-10-30 09:21:18 +01:00
Sébastien Crozet a0fffe93a9 Move the `.shape()` method to its own trait: `Shape`. 2014-10-30 09:21:18 +01:00
Sébastien Crozet 3354ffc37b Make FloatPnt and FloatVec derive from `Index`. 
The point it that `Index` provides the i-th element decomposed into the trivial basis of their
associated vector spaces.
 2014-10-30 08:38:05 +01:00
Sébastien Crozet 2b23446d54 Matrix Index/IndexMut implementation: return an element instead of a column. 
There is no reason why indexing would prefer returning a column instead of a line. Instead, we
return an element, and let the user use the `Col` and `Row` traits istead.
 2014-10-30 08:38:05 +01:00
Sébastien Crozet eb24c4063f Remove the {Any,Float}{Pnt,Vec}Ext traits. 
They are meaningless and too hard to implement in an ad-hoc way to be really useful.
 2014-10-30 08:38:05 +01:00
Sébastien Crozet 074c9356bf Rename: PartialOrd -> POrd, PartialOrdering -> POrdering. 
This avoids name clashes with the standard library.
 2014-10-30 08:38:05 +01:00
Sébastien Crozet a960afa4f9 Make `AnyVec` inherit from `Basis`. 
Every vector must have a basis.
 2014-10-30 08:38:05 +01:00
Sébastien Crozet 2f273d655a Rename: VecExt -> AnyVecExt, PntExt -> AnyPntExt. 2014-10-30 08:38:05 +01:00

Robin Gloster 4e4eb62ffc upgrade to newer rust 2014-10-22 13:35:17 +02:00
Sébastien Crozet e2fc8aa764 Deprecate `to_pnt`, `as_pnt` and `VecAsPnt`. 
Those are meaningless. Use `na::orig() + the_vector` instead.

Sébastien Crozet 276bf3f999 Update to the last rust-nightly. 
Version of rustc: 0.13.0-nightly (222ae8b9b 2014-10-18 00:47:22 +0000).

Fix #26.
 2014-10-12 20:40:46 +02:00
Sébastien Crozet 03eda09084 Some documentation fixes. 
Fix #25.
 2014-10-12 10:35:56 +02:00
Sébastien Crozet b6090042ac Add a `Axpy` that implements y <- y + ax. 
This is very useful for accumulations to compute, e.g. centers.
