RK4TI:
--------------------------------------------------------------------------
Fourth order Runge-Kutta integration. RHS is time-independent (TI).
The right-hand-side function "rhs" computes the state derivative.
"rhs" is a function handle with 2 inputs, evaluated as:
rhs(x,a)
--------------------------------------------------------------------------
Form:
x = RK4TI( rhs, x, h, a )
--------------------------------------------------------------------------
------
Inputs
------
rhs (:) Right-hand side function handle
x (N,1) State (column vector)
h (1) Independent variable step
a (:) Input provided to rhs function
-------
Outputs
-------
x (N,1) Updated state
