**Alberto Ruiz**#### Module documentation for 0.18.0.0

Linear systems, matrix decompositions, and other numerical computations based on BLAS and LAPACK.

Standard interface: `Numeric.LinearAlgebra`

.

Safer interface with statically checked dimensions: `Numeric.LinearAlgebra.Static`

.

Code examples: http://dis.um.es/~alberto/hmatrix/hmatrix.html

## Changes

0.18.0.0

--------

* Many new functions and instances in the Static module

* meanCov and gaussianSample use Herm type

* thinQR, thinRQ

* compactSVDTol

* unitary changed to normalize, also admits Vector (Complex Double)

0.17.0.0

--------

* eigSH, chol, and other functions that work with Hermitian or symmetric matrices

now take a special "Herm" argument that can be created by means of "sym"

or "mTm". The unchecked versions of those functions have been removed and we

use "trustSym" to create the Herm type when the matrix is known to be Hermitian/symmetric.

* Improved matrix extraction (??) and rectangular matrix slices without data copy

* Basic support of Int32 and Int64 elements

* remap, more general cond, sortIndex

* Experimental support of type safe modular arithmetic, including linear

system solver and LU factorization

* Elementary row operations and inplace matrix slice products in the ST monad

* Improved development tools.

* Old compatibility modules removed, simpler organization of internal modules

* unitary, pairwiseD2, tr'

* ldlPacked, ldlSolve for indefinite symmetric systems (apparently not faster

than the general solver based on the LU)

* LU, LDL, and QR types for these compact decompositions.

0.16.1.0

--------

* Added (|||) and (===) for "besides" and "above"

* rowOuters

0.16.0.0

--------

* The modules Numeric.GSL.* have been moved to the new package hmatrix-gsl.

* The package "hmatrix" now depends only on BLAS and LAPACK and the

license has been changed to BSD3.

* Added more organized reexport modules:

Numeric.LinearAlgebra.HMatrix

Numeric.LinearAlgebra.Data

Numeric.LinearAlgebra.Devel

For normal usage we only need to import Numeric.LinearAlgebra.HMatrix.

(The documentation is now hidden for Data.Packed.*, Numeric.Container, and

the other Numeric.LinearAlgebra.* modules, but they continue to be exposed

for backwards compatibility.)

* Added support for empty arrays, extending automatic conformability

(very useful for construction of block matrices).

* Added experimental support for sparse linear systems.

* Added experimental support for static dimension checking and inference

using type-level literals.

* Added a different operator for the matrix-vector product.

(available from the new reexport module).

* "join" deprecated (use "vjoin").

* "dot" now conjugates the first input vector.

* Added "udot" (unconjugated dot product).

* Added to/from ByteString

* Added "sortVector", "roundVector"

* Added Monoid instance for Matrix using matrix product.

* Added several pretty print functions

* Improved "build", "konst", "linspace", "LSDiv", loadMatrix', and other small changes.

* In hmatrix-glpk: (:=>:) change to (:>=:). Added L_1 linear system solvers.

* Improved error messages.

* Added many usage examples in the documentation.

without any conversion.

* GSL special functions moved to separate package hmatrix-special.

Vector is now identical to Roman Leshchinskiy's Data.Vector.Storable.Vector,

so we can convert from/to them in O(1).
