Sébastien Crozet ff95e2a9d8 Remove the shifting from the qr algorithm. 2014-08-17 22:42:16 +02:00
Sébastien Crozet 844092205e Do not compute the matrix inverse if the determinant is near-zero. 2014-08-17 22:41:55 +02:00
Sébastien Crozet 314f0c0043 Add `na::eigen_qr` that performs an eigendecomposition using the qr algorithm. 2014-08-16 15:34:34 +02:00
Sébastien Crozet 663f8b3ccb Add a `Diag` to build, get and set a matrix diagonal. 2014-08-16 13:22:53 +02:00
Sébastien Crozet 40c9915870 Add the types: DVec1, .., DVec6. 
They are stack-allocated, dynamically sized vectors with a maximum size.
This is useful for slicing small matrices, without allocation.
 2014-08-16 12:16:26 +02:00
Sébastien Crozet 7d6884c3df Add a `Det` trait to compute the determinant + implement it for `Mat{1,2,3}`. 2014-08-11 19:54:13 +02:00
Sébastien Crozet 2f0234e7ac Avoid modulo on `DMat::from_fn`. 2014-07-27 09:13:13 +02:00
Nathan Stien ebe1ed1f16 Fix coordinate calculation in DMat::from_fn(). 
The builder function `f` was receiving incorrect coordinates, often
involving a uint underflow.

Added a test case to verify the new behavior.

Sébastien Crozet 5b1388888b Update the compilation section of the README. 2014-07-14 17:56:35 +02:00
Sébastien Crozet 65211aa89a Cleanup the Makefile + update travis.yml. 2014-07-14 16:27:46 +02:00
Sébastien Crozet 11ee4e46b1 Make cargo build a rlib too. 2014-07-14 13:48:31 +02:00
Sébastien Crozet 2ff660dfe1 Add a `ScalarMul` and a `ScalarDiv` trait. 
Those might be useful to overcome rust limitations wrt operator overloading.

Sébastien Crozet 5066d6b9de Update to the last rust-nightly. 
Version of rustc: 0.11.0-pre-nightly (918dbfe 2014-06-02 20:51:30 -0700).
 2014-06-03 22:37:46 +02:00
Sébastien Crozet f6c597f102 Update to the last rust-nightly. 
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).

Sébastien Crozet 40c5f5deb8 Rename matrix-scalar and vector-scalar operator-overloading-related traits to avoid name clashes. 2014-05-22 19:54:54 +02:00

Vincent Barrielle 76a8bc3cf1 QR factorization for fixed size matrices. 
The ColSlice implementation for fixed size matrices returns a DVec,
while this is probably not optimal performance-wise, the dynamic nature
of the result makes this necessary. Using a data type presenting the
ImmutableVector trait would solve this, but it looks like a non-trivial
change.

Alexander Christiansson 5d8727a17d std::cast::transmute -> std::mem::transmute 2014-05-12 01:31:22 +02:00
Vincent Barrielle dcf7b8ad01 generic implementation of QR decomposition 
But static matrices can't use it yet, they need to implement the
Row/Col slicing traits.
 2014-05-11 21:20:41 +02:00
Vincent Barrielle 6ad11edf9b more generic QR: generalize the impl of the Indexable trait 
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.

Vincent Barrielle 5611307b4d QR decomposition depends less on DMat internals 2014-05-09 22:14:37 +02:00
Vincent Barrielle 2fd880a62d implemented QR factorization 
this is a first sketch, the algorithm is not yet initialized and relies
on knowledge of DMat internals. A next step would be to implement this
algorithm in a more generic manner.

Sébastien Crozet 9badebf24c Give access to the traits required for generalized operator overloading. 
Those are `Vec3MulRhs`-like traits that allow the simulation of haskellish fundeps to allow multiple
overloads of builtin operators (* / + -).
They are all on the `na::overload` module.

Sébastien Crozet 7ef933aefb Update to the last Rust. 
Version of rustc: 0.11-pre (eea4909 2014-04-24 23:41:15 -0700)
Vector do not implement `Rand` anymore.
 2014-04-25 20:28:29 +02:00
Sébastien Crozet 1eed234e08 Avoid name conflicts with the standard lib. 
The `Vec` trait is renamed `AnyVec`.
The `Less`, `Greater`, `Equal` variants are renamed `PartialLess`, `PartialGreater`,
`PartialEqual`.

Those new names are not very good, so they might change in the future.
 2014-04-13 10:37:39 +02:00
