I wrote a program.( It indicating this error:Struct contents reference from a non-struct array object.)please help me,where the error is?

clear all;
close all;
Nt=2;
Nr=2;
alpha=1;
Pb=10^-3;
b=2;
B=10000;
No=(7.94*10^-21);
GtGr=3.162;
dij=100;
lambda=0.12^2;
Ml=10;
Nf=0.01;
ptc=47.8*10^-3;
prc=69.8*10^-3;
psyn=50*10^-3;
Ebt=[];
for i=1:length(Nt);
    for j=1:length(Nr);
        Ebt=((1+alpha)*(Pb/4^(-1/Nt*Nr))*(2^b-1)/b^((1/Nt*Nr)+1)*(7.94*10^-21)*(((4*pi*dij)^2)/GtGr*lambda)*(Ml*Nf)+((Nt*ptc+2*psyn+Nr*prc)/B.b));
    end
end
disp(Ebt);

The error is in the for loop, where you typed something like

 B.b

at the end. I am not sure what you tried to do with it. The compiler will treat B as a struct and try to reach its field b but it will throw an error since B and b are different numeric variables. Please check that.
