EDIT
A=[2 4 5
6 8 9
1 3 4 ];
A_1_10 = A(:,:,ones(10,1));
k = nchoosek(1:9,3);
k2 = k(all(diff(k,1,2)>1,2),:)
k3 = k2(1:floor(size(k2,1)/10):end,:)
A_1_10(bsxfun(@plus,k3(1:10,:),(0:9:9^2).')) = 0

So you want to have random number, but always the same set of random numbers? Check out RandStream.

Kash, you answer before checking RandStream. That way you happen to give a comment that make you appear "less intelligent than you'd want to". Check out the documentation of RandStream, then answer.
