question on matlab compatible ode solver : parameters

[Tatsuro MATSUOKA]

On the octave dev source

>> help ode45

 -- [T, Y] = ode45 (FUN, TRANGE, INIT)
 -- [T, Y] = ode45 (FUN, TRANGE, INIT, ODE_OPT)
 -- [T, Y] = ode45 (..., PAR1, PAR2, ...)
 -- [T, Y, TE, YE, IE] = ode45 (...)
 -- SOLUTION = ode45 (...)


 -- [T, Y] = ode45 (..., PAR1, PAR2, ...)
seems to accept parameter.

However, in MATLAB documents. 

http://jp.mathworks.com/help/matlab/ref/ode45.html?lang=en

[t,y] = ode45(odefun,tspan,y0)example
[t,y] = ode45(odefun,tspan,y0,options)example
[t,y,te,ye,ie] = ode45(odefun,tspan,y0,options)
sol = ode45(___)


There are no description for parameter arguments.
Use of anonymous function of functions with parameters are considered.


 -- [T, Y] = ode45 (..., PAR1, PAR2, ...)

Is the  implementation octave original and for backward compatibility in odepkg 
solvers ?.


Am I write?
