Function handles cannot be passed to extrinsic functions.

Hi,

I'm using a Matlab Function Block in simulink to calculate the minimum value of a objective function with constraints.

I get this error during my simulation:

Function handles cannot be passed to extrinsic functions.
Function 'MaxRange ' (#106.382.388), line 25, column 13: "@nlfun"
Launch diagnostic report.

Below are my codes:

function y=minLoss(a,b,c,d,e)
coder.extrinsic('fmincon');
global Pload;
global R1;
global R2;
global Vocv1;
global Vocv2;
Pload=a;
R1=b;
R2=c;
Vocv1=d;
Vocv2=e;
x0=[1;-1];
A=[];B=[];
Aeq=[];Beq=[];
LB=[];UB=[];
num.of.bat.pack=2;
y = coder.nullcopy(zeros(size(num.of.bat.pack)));
[y]=fmincon(@nlfun,x0,A,B,Aeq,Beq,LB,UB,@nlcon);
function f=nlfun(x)
global R1;
global R2;
f=R1*x(1)^2+R2*x(2)^2;
function [g,ceq]=nlcon(x)
global Pload;
global R1;
global R2;
global Vocv1;
global Vocv2;
g=[];
ceq=Vocv1*x(1)-R1*x(1)^2+Vocv2*x(2)-R2*x(2)^2-Pload;
nlfun is my objective function.
nlcon is my constraint function.
inputs (a,b,c,d,e) are the parameters for nlfun and nlcon.
