RKF Uses a list [z)—containing the name of the time
variable, the name of the solution variable, and the
differential fimction—and the absolute error
tolerance (^) to compute the solution of the initial
value problem at a point (r) using the
Rimge-Kutta-Fehlberg (4,5) method.

RKFERR Uses a list (y)—containing the name of the time
variable, the name of the solution variable, and the
differential fimction—and a possible step size (.r)
to compute the change in solution and an absolute
error estimate for that step using the
Runge-Kutta-Fehlberg (4,5) method.

RKFSTEP Uses a list (z)—containing the name of the time
variable, the name of the solution vai'iable, and the
differential function—and a possible step size (r)
to compute the next solution step of the initial
value problem using the Runge-Kutta-Fehlberg
(4,5) method such that the specified absolute error
tolerance ( 2 /) is satisfied.
