I am pleased to announce a new version of hmatrix: 0.19.0.0.
This is not intended to be a breaking change but a lot of modules have =
been modified to ensure that continuous integration (which has now been =
set up) is green.
Support for SUNDIALS <https://computation.llnl.gov/projects/sundials> =
has been added. It should be possible to replace Numeric.GSL.ODE with =
Numeric.Sundials.ARKode.ODE and have your program work as before bearing =
in mind that the methods and error control might differ (even for those =
with the same names!).
The packages that comprise hmatrix are:
hmatrix
hmatrix-gsl
hmatrix-special
hmatrix-sparse
hmatrix-glpk
hmatrix-tests
hmatrix-sundials
I am planning to split these up into separate projects to make it easier =
for contributors. To this end, I have created an hmatrix =
<https://github.com/haskell-numerics> organisation in github. Please =
contact me if you wish to become a member.
I strongly recommend anyone solving ODEs to look as hmatrix-sundials as =
the underlying package provides many more methods, more documentation =
and more diagnostic information (great when your 200 variable model =
fails). It is a truism that any sufficiently sophisticated ODE solver =
package is a domain specific language (I include the ODE solving part of =
GSL here). The current interface both to GSL and to SUNDIALS is somewhat =
rudimentary but will hopefully evovle to a nicer DSL (something at which =
Haskell excels).
