Sorry, my mistake. The _no. of integers_ generated must be in the range 2 to m.

The condition is that each row must contain _at least_ two non-zero integer values.
Therefore, each row should have 'a' zeros ('a' ranges from 0 to m-2) and 'b' integers ('b' ranges from 2 to m). The values of the integers are 1,2,...,m - a.

For example, take the first row(m=6). It has two zeros (a=2) and b = m - 2 = 4. Therefore, the values of integers = 1,2,3,4.

Also, is there any command to randomly arrange a given set of random numbers, say {13,4,5,6,2} ?
