advance ode t modifies
ode so that an approximation of the
value of the solution at times
t is computed.
lsoda f y0 t0 t solves the ODE dy/dt = F(t,y) with initial
sol ode t modifies
ode so that it holds an approximation of
the solution at
t and returns this approximation.
t ode returns the current time at which the solution vector was
vec ode returns the current value of the solution vector.
