RRK Uses a hst (z)—containing the name of the time
variable, the name of the solution variable, the
differential function and its first two derivatives—
and the absolute error tolerance (^) to compute
the solution of the initial value problem at a point
(x’) using the Rosenbrock and Runge-Kutta
methods.

RRKSTEP Uses a hst (t) —containing the name of the time
variable, the name of the solution variable, the
differential fimction and its fii’st two derivatives—
the absolute error tolerance
( 2 ),
a possible step
size (t/), and a value (x) indicating the solution
method used in the previous step. Computes the
next solution step of the initial value problem
using a combination of Rosenbrock and
Runge-Kutta methods.

RSBERR Uses a hst {y)—containing the name of the time
variable, the name of the solution variable, the
differential function, and its first two derivatives—
and a possible step size (x) to compute the change
in solution and an absolute error estimate for that
step using a combination of Rosenbrock and
Runge-Kutta methods.
