parse error at '[', '=',')'.

I am getting error at "b[j]=norm(X,1);" as: parse error at '[', '=',')'. How should i rectify it?

function [b]=rf(l,k,H,d)

b=zeros(1,Nu);

for j=0:Nu-1

   X= H'*d(:,j);
    b[j]=norm(X,1);

end

end

[Birdman]

   b[j]=norm(X,1);

This line should be

 b(j)=norm(X,1);
