Hi Sir, kindly tell me where i am doing wrong??
TN=4;
n_vec=1:TN;
n=n_vec;
max=[0.32 0.51 0.112 1.3];
B=0.3;
Psi=0.6;
No=0.01;
tau=B./n;
for Max=max;
h=rand(1,TN);
Rhn=(tau*Psi*log(2))*(1+((max*h)/(tau*No)))
end

TN=4;
n_vec=1:TN;
n=n_vec;
themax=[0.32 0.51 0.112 1.3];
B=0.3;
Psi=0.6;
No=0.01;
tau=B./n;
for Max=themax;
h=rand(1,TN);
Rhn=(tau*Psi*log(2)).*(1+((themax.*h)./(tau*No)))
end
Read about element by element array operations. When you multiply arrays element by element use .*.
Also note that, don't name the variables on the name of inbuilt functions......I have renames variable max with themax. There is inbuilt function to find maximum called max.

Don't name variable max because there is an inbuilt function named max(), preallocate Rhn for speed and efficiency:
TN=4;
n_vec=1:TN;
n=n_vec;
Max=[0.32 0.51 0.112 1.3];
B=0.3;
Psi=0.6;
No=0.01;
tau=B./n;
Rhn=zeros(TN);
for k=1:TN
h=rand(1,TN);
Rhn(k,:)=(tau*Psi*log(2))*(1+((Max(k)*h)/(tau*No)));
end
Rhn
