Using .mexw64 in a Matlab function

Hi,
I'm trying to simulate a Rankine Cycle in Matlab. To calculate the water properties, I'm using the coolprop package http://www.coolprop.org/coolprop/wrappers/MATLAB/index.html#matlab.
I wrote a script (see below) and it works perfectly. Now, I want to rewrite it into a Matlab function in orden to simulate the cycle with the Simulink block MATLAB function, but it doesn't work: "Only MATLAB files are supported for code generation. Unsupported file extension 'mexw64' for C:\....".
What can I do?
Here's the script I want to rewrite into a function:
clear all
clc
close all
%COOLPROP
addpath('C:\Program Files\MATLAB\R2015b')
% 1:
P1 = 8e6
Q1 = 1
H1 = CoolProp.PropsSI('H','P',P1,'Q',Q1,'Water')
S1 = CoolProp.PropsSI('S','P',P1,'Q',Q1,'Water')
T1 = CoolProp.PropsSI('T','P',P1,'Q',Q1,'Water')
% 2:
display('Propiedades del agua a la entrada del condensador')
S2 = S1
P2 = 0.008e6
T2 = CoolProp.PropsSI('T','P',P2,'S',S2,'Water')
H2 = CoolProp.PropsSI('H','P',P2,'S',S2,'Water')
% 3:
P3 = P2
Q3 = 0
H3 = CoolProp.PropsSI('H','P',P3,'Q',Q3,'Water')
S3 = CoolProp.PropsSI('S','P',P3,'Q',Q3,'Water')
T3 = CoolProp.PropsSI('T','P',P3,'Q',Q3,'Water')
% 4:
S4 = S3
P4 = P1
H4 = CoolProp.PropsSI('H','P',P4,'S',S4,'Water')
T4 = CoolProp.PropsSI('T','P',P4,'S',S4,'Water')
% MORE
Wt_m = H1 - H2;
Wp_m = H4 - H3;
Qin = H1 - H4;
Wc = 100e6*3600;
nu = 100 * (Wc/Qin)

Hi Ana,
The below link may be helpful to resolve the issue. The functions may need to be declared using coder.extrinsic since the coolprop package seems to use mex files:
Hope this helps!
