How can I compile a call to a ODE with a parameterized function? Lets take the example from ode45:
function y = odeTEST()
A = 1;
B = 2;
tspan = [0 5];
y0 = [0 0.01];
[t,y] = ode45(@(t,y) odefcn(t,y,A,B), tspan, y0);
end
function dydt = odefcn(t,y,A,B)
dydt = zeros(2,1);
dydt(1) = y(2);
dydt(2) = (A/B)*t.*y(1);
end
save them as .m files and and compile it with
codegen -config:dll odeTEST
it will give me
??? Anonymous functions are not supported for code generation
(This is related, but not identical to my other question on generating DLLs)

As of MATLAB R2016b, code generation with MATLAB Coder supports anonymous functions:
In prior releases, you can mimic them using persistent variables as shown here:
