Sundials/ML
Keywords: Simulation - Mathematics - Numerical simulations
Scientific Description: Sundials/ML is a comprehensive OCaml interface to the Sundials suite of numerical solvers (CVODE, CVODES, IDA, IDAS, KINSOL). Its structure mostly follows that of the Sundials library, both for ease of reading the existing documentation and for adapting existing source code, but several changes have been made for programming convenience and to increase safety, namely:
solver sessions are mostly configured via algebraic data types rather than multiple function calls,
errors are signalled by exceptions not return codes (also from user-supplied callback routines),
user data is shared between callback routines via closures (partial applications of functions),
vectors are checked for compatibility (using a combination of static and dynamic checks), and
explicit free commands are not necessary since OCaml is a garbage-collected language.
Functional Description: Sundials/ML is a comprehensive OCaml interface to the Sundials suite of numerical solvers (CVODE, CVODES, IDA, IDAS, KINSOL, ARKODE).
Release Functional Description: Adds support for v3.1.x of the Sundials Suite of numerical solvers.
Notably this release adds support for the new generic matrix and linear solver interfaces. The OCaml interface changes but the library is backward compatible with Sundials 2.7.0.
OCaml 4.02.3 or greater is now required and optionally OCamlMPI 1.03.
* New Sundials.Matrix and Sundials.LinearSolver modules. * Better treatment of integer type used for matrix indexing. * Refactor Dls and Sls modules into Sundials.Matrix. * Add confidence intervals to performance graph. * Miscellaneous improvements to configure script. * Potential incompatibility: changes to some label names: comm_fn -> comm, iter_type -> iter. * Untangle the ARKODE mass-solver interface from the Jacobian interface.
