   mb1=10*mb;
in the middle band
   A=ones(8);
   for i=1:4
     for j=8-(i+2):8
       A(i,j)=0;
     end
   end
   for i=5:8
     for j=1:8-(i-4)
       A(i,j)=0;
     end

Best Answer

No one knows what you mean. You have two matrices, mb and mb1. And then you create a new matrix, A, that is all zeros. Do you want mb1 to come after row 4 of A and then A picks up again after MB1 is done? If so do
output = [A(1:4,:); mb1; A(5:end, :)];
