Hi I need help to convert Matlab Code file to a MATLAB system in Simulink.

For an example the coded function below have been made in the terms of code file. However, when I try to recall the function from MATLAB System, it says it's not a system object.

function [dCadt,dTdt] = reactor1(Ca, T)
Ea=4800;    
k0=1e12;    
dH=5000;    
U=15;        
rhocp=0.2;  
R=1.7;     
V=70;       
F=6000;      
Caf=1.32;   
Tf=40;       
A=11;      
Tj=80.9;
dCadt=((F/V)*(Caf-Ca))-(k0*Ca*exp(-Ea/(R*(T+460))));
dTdt=((F/V)*(Tf-T))-(dH)/(rhocp)*(k0*Ca*exp(-Ea/(R*(T+460)))-(U*A)/(rhocp*V)*(T-Tj));

What is the exact error you are getting? Can you give a snapshot of that?

Is the function script in the working path?

Illustrated below is the step-by-step action on what I did to convert the MATLAB Code in Step 2 into the MATLAB System shown in Step 1. However, when I try to define the system object. An error was found, displayed as in Step 3.
