How can I call a function (with all its parameters) using another function?

I have defined the following function: (part of the code is omitted for simplicity)

function [t,y]= backEulerfedbatchSystem(rhs,drhs,x0,t0,tf,n)

In particular the parameter "rhs" is also a function defined by:

function dxdt = FedbatchFermenterModel(t,x,u,d,par)

When I call this function in this way:

backEulerfedbatchSystem(FedbatchFermenterModel,drhs,x0,t0,tf,n)

An error occurs. FedbatchFermenterModel cannot be computed because it lacks its parameters (t,x,u,d,par). How can I call the function FedbatchFermenterModel (with all its parameters) using backEulerfedbatchSystem? Any hint will be appreciated !

backEulerfedbatchSystem(@FedbatchFermenterModel, drhs, x0, t0, tf, n)

then inside the function,

rhs(t, x, u, d, par)

but you have to figure out u, d, par inside backEulerfedbatchSystem.

Are those parameters possibly known at the time backEulerfedbatchSystem is being called? If so, then

backEulerfedbatchSystem(@(t, x) FedbatchFermenterModel(t, x, u, d, par), drhs, x0, t0, tf, n)

and then inside the function,

rhs(t, x)
