SUNDIALS (SUite of Nonlinear and DIfferential/ALgebraic equation Solvers) consists of the following five solvers:

CVODE solves initial value problems for ordinary differential equation (ODE) systems.
CVODES solves ODE systems and includes sensitivity analysis capabilities (forward and adjoint).
ARKODE solves initial value ODE problems with additive Runge-Kutta methods, include support for IMEX methods.
IDA solves initial value problems for differential-algebraic equation (DAE) systems.
IDAS solves DAE systems and includes sensitivity analysis capabilities (forward and adjoint).
KINSOL solves nonlinear algebraic systems.

In addition, SUNDIALS provides a Matlab interface to CVODES, IDAS, and KINSOL, sundialsTB. [Note: sundialsTB has not been updated in release v. 2.6.0.  We expect to update this in a future release.]
