How do I fill a 1000*25 length vector with random, non-repetitive numbers from 1 to 1000000?

I tried numerous ways of doing the above but I keep getting compatibility issues since randperm(1000000) returns a vector of length 1000000 and my created vector is just 1000*25.

a=zeros(1000,25);
a(:)=randperm(1000000, numel(a));
