Repeating exactly the same phrase three times for your heading, description and tag does not really help us to understand your question. You have not explained if you want integers or decimal random numbers, or what distribution they should have, or any other special conditions that you might have. We cannot read minds, so if you do not tell us then we don't know!

You can use randi to generate uniformly distributed integer values:

>> randi(6, [5,6])
ans =
   5     6     6     3     3     2
   2     4     2     2     5     5
   4     1     5     2     4     5
   5     1     2     4     4     3
   6     2     6     3     6     4
>> randi(6, [5,6])
ans =
   1     1     1     4     3     5
   1     4     5     2     1     4
   4     3     2     4     2     6
   5     1     4     5     6     1
   6     3     1     5     1     3

If you want uniformly distributed decimal values, then use rand:

>> 1+5*rand([5,6])
ans =
     1.5333       5.3435       3.1571       1.6803       5.2652       1.3798
     5.8095       1.4222       5.5532       5.3465       4.1103       2.1996
     1.0232       2.9989       1.9092       3.8985       2.7548       1.6166
     4.8746       2.2994        2.319       3.7493       3.5662       1.9195
     5.0865       5.0003       1.7277       1.7248        3.009       2.1998
>> 1+5*rand([5,6])
ans =
     3.0863       3.4463       4.9013       1.6599       2.1739        1.845
     1.2483       2.6886       2.9487       5.7103       2.7658       4.2456
     5.5136       5.5003       2.2085       5.7807        5.106       4.6586
     5.7239       2.8462       3.0196        3.876        1.077       4.2387
     3.4543        1.556       1.4823       1.2989       1.2151       3.2546

And of course remember that no computer-based "random" number is truly random.

sorry,my bad..i want an integer number between 1-6.is that randi same with randperm?as i need different range of number(1-6) for each row

Sorry, it is not clear to me what result you want. Please give a more detailed description, or provide an example of the output that you want.
