### Added
- Add `Cholesky::ln_determinant` to compute the natural logarithm of the determinant of a matrix decomposed
with Cholesky. This can be more numerically stable than computing the determinant itself when very small and/or
large values are involved.

feature must be enabled to access these methods.

## [0.25.1]
This release replaces the version 0.25.0 which has been yanked. The 0.25.0 version
added significant complication to build `nalgebra` targeting a `#[no-std]` platform
not supported by `rand`.
The `rand` dependency is now optional (and disabled by default). You may enable it with:
- The `rand-no-std` cargo feature when targeting a `#[no-std]` environment.
- The `rand` cargo feature when targeting a `std` environment.
## [0.25.0] - Yanked
This updates all the dependencies of nalgebra to their latest version, including:
- rand 0.8
- proptest 1.0
- simba 0.4
### New crate: nalgebra-sparse
Alongside this release of `nalgebra`, we are releasing `nalgebra-sparse`: a crate dedicated to sparse matrix
computation with `nalgebra`. The `sparse` module of `nalgebra`itself still exists for backward compatibility,
but it will be deprecated soon in favor of the `nalgebra-sparse` crate.
### Added
* Add `UnitDualQuaternion`, a dual-quaternion with unit magnitude which can be used as an isometry transformation.
* Add `UDU::new()` and `matrix.udu()` to compute the UDU factorization of a matrix.
* Add `ColPivQR::new()` and `matrix.col_piv_qr()` to compute the QR decomposition with column pivoting of a matrix.
* Add `from_basis_unchecked` to all the rotation types. This builds a rotation from a set of basis vectors (representing the columns of the corresponding rotation matrix).
* Add `from_basis_unchecked` to all the rotation types. This builds a rotation from a set of basis vectors (representing
the columns of the corresponding rotation matrix).
* Add `Matrix::cap_magnitude` to cap the magnitude of a vector.
* Add `UnitQuaternion::append_axisangle_linearized` to approximately append a rotation represented as an axis-angle to a rotation represented as an unit quaternion.
* Add `UnitQuaternion::append_axisangle_linearized` to approximately append a rotation represented as an axis-angle to a
rotation represented as an unit quaternion.
* Mark the iterators on matrix components as `DoubleEndedIter`.
* Re-export `simba::simd::SimdValue` at the root of the `nalgebra` crate.
## [0.24.0]
### Added
* The `DualQuaternion` type. It is still work-in-progress, but the basics are here:
creation from its real and dual part, multiplication of two dual quaternions,
and normalization.
### Removed
* There is no blanket `impl<T> PartialEq for Unit<T>` anymore. Instead, it is
implemented specifically for `UnitComplex`, `UnitQuaternion` and `Unit<Vector>`.
## [0.23.2]
In this release, we improved the documentation of some of the geometric types
by applying changes similar to what we did in the version 0.23.1 for matrices.
### Added
* The `Isometry::inv_mul` method which is a more efficient way of doing
`isometry1.inverse() * isometry2`.
## [0.23.1]
In this release we improved the documentation of the matrix and vector types by:
- Grouping `impl` bocks logically, adding a title comment to these impl blocks.
- Reference these impl blocks docs at the top of the documentation page for `Matrix`.
- Reduce the depth of type aliasing. Now all vector and matrix types are aliases of `Matrix`

operations with nalgebra in a `no-std` environment, you will need to enable the new `libm` feature

geometric types.
### Modified
* Use of traits like `alga::general::{RealField, ComplexField}` have now been replaced by
`simba::scalar::{RealField, ComplexField}`.
* The implementation of traits from the __alga__ crate (and well as the dependency to _alga__) are now
omitted unless the `alga` cargo feature is activated.
### Removed
* The `Neg` unary operator is no longer implemented for `UnitComplex` and `UnitQuaternion`. This caused
hard-to-track errors when we mistakenly write, e.g., `-q * v` instead of `-(q * v)`.
* The `na::convert_unchecked` is no longer marked as unsafe.

* `.try_set_magnitude(...)` which sets the magnitude of a vector, while keeping its direction.
* Implementations of `From` and `Into` for the conversion between matrix slices and standard (`&[N]` `&mut [N]`) slices.
### Modified
* We started some major changes in order to allow non-Copy types to be used as scalar types inside of matrices/vectors.
## [0.19.0]
### Added
* `.remove_rows_at` and `remove_columns_at` which removes a set of rows or columns (specified by indices) from a matrix.
* Several formatting traits have been implemented for all matrices/vectors: `LowerExp`, `UpperExp`, `Octal`, `LowerHex`,
`UpperHex`, `Binary`, `Pointer`.
* `UnitQuaternion::quaternions_mean(...)` which computes the mean rotation of a set of unit quaternions. This implements

`::reversed_perspective_rh_zo`, and `::reversed_infinite_perspective_rh_zo`.
## [0.18.0]
This release adds full complex number support to nalgebra. This includes all common vector/matrix operations as well
as matrix decomposition. This excludes geometric type (like `Isometry`, `Rotation`, `Translation`, etc.) from the
`geometry` module.
### Added

* Add `.left_div, .right_div` for quaternions.
* Add `.renormalize` to `Unit<...>` and `Rotation3` to correct potential drift due to repeated operations.
Those drifts could cause them not to be pure rotations anymore.

#### Complex number support
* Add the `::from_matrix` constructor too all rotation types to extract a rotation from a raw matrix.
* Add the `::from_matrix_eps` constructor too all rotation types to extract a rotation from a raw matrix. This takes
more argument than `::from_matrix` to control the convergence of the underlying optimization algorithm.

* Add `.camin()` which returns the matrix component with the smallest L1-norm.
* Add `.ad_mul(b)` for matrix-multiplication of `self.adjoint() * b`.
