MATLAB: Matlab not giving several matrices against a for loop

for loopmatrices

I am applying for loop on a variable n to get corresponding matrices against each value of n but Matlab only uses the last value of n and gives the single matrix. Will be grateful to anyone who can help
if true
  % code
Nt=3;Nm=-3;b=0.5;
%Define E(j,k)
for k=0:Nt-1
  for j=0:Nt-1
      if j~=k
          e(j+1,k+1)= 0; 
     elseif j==k~=0
         e(j+1,k+1)= pi/2;
       else e(j+1,k+1) = pi;
      end
      %Define D(j,k)
      if mod(abs(k-j),2)==0
          d(j+1,k+1)= pi/2*k*(k^2-j^2);
      else d(j+1,k+1)=0;
      end
      %Define A(n) matrix
    for n=-3:3
        if j<=Nt-3
          a(j+1,k+1)=-(n*b)^2*e(j+1,k+1)+d(j+1,k+1);
      elseif j==Nt-2
          a(j+1,k+1)=1;
      else a(j+1,k+1)=(-1)^k;
        end
    end
  end
end
end

Your code runs without error and your ‘a’ matrix is (3x3). What do you want?
