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.

Can anyone kindly advise on what actually went wrong? Much Thanks in advance!

Thank you, I checked out that and it actually worked.
