Start with a simple pattern that works, and then randperm both the rows and columns. E.g.,
B = zeros(10);
for k=1:10 % start with a simple pattern that works
B(k,:) = mod(k-1:k+8,10) + 1;
end
B = B(randperm(10),randperm(10)); % permute the rows and columns
Sample run:
>> batting_order
>> B
B =
4 6 2 10 7 3 8 5 9 1
3 5 1 9 6 2 7 4 8 10
10 2 8 6 3 9 4 1 5 7
6 8 4 2 9 5 10 7 1 3
5 7 3 1 8 4 9 6 10 2
7 9 5 3 10 6 1 8 2 4
2 4 10 8 5 1 6 3 7 9
1 3 9 7 4 10 5 2 6 8
8 10 6 4 1 7 2 9 3 5
9 1 7 5 2 8 3 10 4 6
