-# [hmatrix][hmatrix2] installation
-
-This package requires the [Glasgow Haskell Compiler](http://www.haskell.org/ghc/index.html) ghc >= 6.10, and [cabal-install](http://www.haskell.org/haskellwiki/Cabal-Install), conveniently available in the [Haskell Platform](http://hackage.haskell.org/platform), and the development packages for [GSL](http://www.gnu.org/software/gsl) and BLAS/[LAPACK](http://www.netlib.org/lapack). (The graphical functions also require **gnuplot** and **imagemagick**.)

-Arch Linux: If the automatic installation from Hackage fails, install atlas-lapack and gsl, unpack the source, change the build-type to Simple in hmatrix.cabal (line 28) and add extra-libraries: gsl lapack (line 194).

-If you get any failure please run lapack's own tests to confirm that your version is not broken. For instance, in ubuntu 9.04, **libatlas-sse2** does not work (see this [bug report](https://bugs.launchpad.net/ubuntu/+source/atlas/+bug/368478)). If your lapack library is ok but hmatrix's tests fail please send a bug report!

-## Optimized BLAS/LAPACK ##########################################
-
-I have successfully tested ATLAS and MKL on Linux.
-
-### [ATLAS](http://math-atlas.sourceforge.net/)  ####################
-
-In Ubuntu >= 9.04 we need:
-
-    $ sudo apt-get install libatlas-base-dev
-
-In older Ubuntu/Debian versions we needed:
-
-    $ sudo apt-get install refblas3-dev lapack3-dev atlas3-base-dev
-
-We may use a version (sse2, 3dnow, etc.) optimized for the machine.
-
-### Intel's MKL  ###############################################
-
-There is a free noncommercial download available from Intel's website. To use it I have added the following lines in my .bashrc configuration file:
-
-    export LD_LIBRARY_PATH=/path/to/mkl/lib/arch
-    export LIBRARY_PATH=/path/to/mkl/lib/arch
-
-where arch = 32 or em64t.
-
-The library must be installed with the -fmkl flag:
-
-    $ cabal install hmatrix -fmkl
