Dear all,
I am studying on testing PRNG and I have problem in using Diehard and Dieharder. This intruction in Diehard's document (Marsaglia) is not clear to me: _
Your random number generator should produce 32-bit integers.
(If 31 bits, left justify by shift-left-one, as some of the
tests in DIEHARD favor leading bits.) You should send them to
your ascii file in hex form, 8 hex 'digits' per integer,
10 integers per line, no intervening spaces. The ascii file
will be twice as big as the binary file it is reduced to._
In fact, I generated random number by using Matlab to implement some algorithm and also obtained the integer numbers. But I am not sure how to make a test file which is used as an input for Diehard or Dieharder. I hope to hear from you in detail about my problem.
Thank you,

fprintf(fid, [repmat('%08x', 1, 10), '\n'], YourVector)

If you want to run all 15 Diehard tests at once, make sure your data files contain about 2.5 million numbers. They will be about 10 megabytes in size.
