# Solvers and Test Set for Initial Value Problems of Ordinary Differential Equations (ODE), Partial Differential Equations (PDE) and for Differential Algebraic Equations (DAE)

### Description

R package deTestSet contains the R-version of the ODE and DAE initial value problems test set from http://www.dm.uniba.it/\~testset.

If the test model problem is small enough, then it is implemented in pure R. For larger models, the problem is specified in FORTRAN code.

These implementations were compiled as DLLs, and included in the package. The code of these models can be found in the packages inst/doc/examples/dynload subdirectory.

In addition to all solvers present in package `deSolve`

,
`deTestSet`

contains the initial value problem solvers
`gamd`

, and `mebdfi`

, implementing a generalised adams method
and a differential algebraic equation solver of index up to three.
