Hi, I've been tested so many times and tried all the answers from here and still not working.
if the expression is
with
m=4.541*TN*S0/T
T=1:0.1:100
TN=70
S0=0.99
integration with simpson 1/3
here my code:
clear all; clc;
f1=inline('3/2*(cos(x)^2)*exp(m*(3/2*(cos(x)^2))-1/2)*sin(x)','m','x');
f2=inline('exp(m*(3/2*(cos(x)^2)-1/2))','m','x');
T0=1;
TM=100;
dT=0.1;
TN=70;
S0=0.99;
for T=T0:dT:TM;
m=4.541*TN*S0/T;
a=0;b=pi;
c=0;d=pi;
n=100;
h=(b-a)/n;
f1a=f1(a);f1b=f1(b);
f2a=f2(a);f2b=f2(b);
jumeven=0;jumodd=0;
for i=1:n-1
p=mod(1,2);
if p==0
xi=x+i*h;
jumeven=jumeven+f(xi);
else
xi=x+i*h;
jumodd=jumodd+f(xi);
end
end
I1=(h/3)*(f1a+4*jumodd+2*jumeven+f1b);
I2=(h/3)*(f2c+4*jumodd+2*jumeven+f2d);
S=I1/I2;
S0=S;
end
disp([S' T']);
disp([S]);
plot(S,T,'ob-','linewidth',3);
grid on;
xlabel('S','fontsize',18);
ylabel('T','fontsize',18);

"it's already in my lecturer's guide."
Your lecturer wrote their (mis)guide back in the dark ages. You should ask for your money back.
"And btw, any suggestion from you? I'm happy to try it"
You do what the MATLAB documentation recommends:

f1 = @(m,x) 3/2*(cos(x).^2).*exp(m.*(3/2*(cos(x).^2))-1/2).*sin(x);
f2 = @(m,x) exp(m.*(3/2*(cos(x).^2)-1/2));

These lines:
f1a=f1(a);f1b=f1(b);
f2a=f2(a);f2b=f2(b);
Should be:
f1a=f1(m,a);f1b=f1(m,b);
f2a=f2(m,a);f2b=f2(m,b);
As the functions f1, f2 need two inputs.
