How insert this value
mb=[5 6 7 4 5 6 7 8 9 10 11 12 7 8 14 15 16 17 18 ...
7 8 19 21 23 25 27 29 7 20 22 24 26 28 1 2 1 2 1 2 1 2 1];
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
end

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, :)];

For replacement , rather than insertion , you'd want this:
A(5:6, :) = mb1; % Replace rows 5 and 6 with mb1

Reem's "Answer" moved here since it's not an "Answer" to the originally posted question:
This result
1 1 1 1 50 60 70 80
1 1 1 40 50 60 70 80
1 1 90 100 110 120 70 80
1 140 150 160 170 180 70 80
190 210 230 250 270 290 70 1
200 220 240 260 280 300 1 1
10 20 10 20 10 1 1 1
20 10 20 10 1 1 1 1

I didn't know until I ran your code that the "band" is a group of 0's running diagonally from the upper right of the array to the lower left of the array. Anyway, do you have what you need now? If not, give the desired array after reading this.
