Hi everyone , I need to calculate inverse of A(v,n,m+N+1) for 3rd dimension , I mean array B, but there are zeros here and I can't calculate inverse for all m because matrix is singular.Here is the code;

    for m=-N:N
        if m==0
           k=1;
         else 
           k=abs(m);
          end
         for v=k:N
           for n=k:N
              A(v,n,m+N+1)=(v+n)*m;
             end
           end
         end 
    for i=1:2*N+1
        B(:,:,i)=inv(A(:,:,i);
       end
