I am using this program and I get a message saying that my licence is not valid

clf
Npt=128;
d=0.2;

%calcul de la differencielle de l'integrale de delta
%v=repmat(0,[Npt,Npt,Npt]);
v=zeros(Npt,Npt,Npt);
v(5:Npt-5,5:Npt-5,5:Npt-5)=0.9;
v(30:70,30:70,30:70)=0.05;
v(14:17,14:17,14:17)=0.5;
%v(15:16,15:16,15:16)=1;

v=v*1e-6;
pix=1.4e-6;
T=sum(v,3)*pix;
A=diff(T,2,1)/pix^2;
[N1A, N2A]=size(A);
 A(N1A:Npt,:)=0;
B=diff(T,2,2)/pix^2;
[N1B, N2B]=size(B);
 B(:,N2B:Npt)=0;

%calcul de mu
mu=v*1e-9;
u=sum(mu,3);

%calcul du second terme
Z=u-d*(A+B);

I=I0./(exp(Z));
