The Chicken sundials library provides bindings to the solvers from the SUNDIALS library. SUNDIALS (SUite of Nonlinear and DIfferential/ALgebraic equation Solvers) is a collection of solvers for systems of ordinary differential equations and differential-algebraic equations.
The Chicken sundials library provides interfaces to the CVODE and IDA solvers and has been tested with SUNDIALS version 2.4.0.

[RESIDUAL-INIT] [RESIDUAL-EVENT] [ALG-OR-DIFF] [SUPPRESS] [IC] [USER-DATA] [EVENTS] [RELTOL] [ABSTOL])</procedure>
Creates and initializes an object representing a problem to be solved with the IDA solver.
Arguments TSTART and TSTOP are real numbers that represent the beginning and end of the independent variable range.
Arguments VARIABLES and DERIVATIVES must be SRFI-4 f64vector objects that hold respectively the initial values and derivatives of the system variables.
Argument RESIDUAL-MAIN computes the residual function F and must be a procedure of the following form:
(LAMBDA T YY YP RR DATA)
- real-valued independent variable
- SRFI-4 f64vector with current variable values
- SRFI-4 f64vector with current variable derivatives
- SRFI-4 f64vector residual vector, which must be set by this procedure
- is a user data object (if set)
(with-server-connection h "localhost" 11211 (let ((foo 4)) (let ((success (set h "foo" foo))) (let ((foo1 (get h "foo"))) (equal? foo foo1)))))
