Sir

i want to make an array of [16*8] random number of [1,16] in which
every column have non repeating number and row elements are not same.

Assuming that you intend to have each column of your
array a permutation of the numbers 1:16, then simplest
is just to use a random sample for the first column, then
generate a new random sample for the second column.
Reject if there are any conflicts, and repeat for each
column, one at a time. This will get more difficult by
the time you go out 8 columns.

As I said, simple, but not very efficient.
