what should I do with rand() so that the sum of each row should not be greater than one??..

I generated the random numbers from 0 to 1 as follows:
Population = rand(20,3)
now I wants that the sum of each individual row should not be greater than zero
s = sum(Population,2)
how should I restrict each row, generated with rand(), so that the its sum should be b/w 0 and 1??...
The values in each row should come as if I add them up they should not exceed one
plZ answer it.....

"should not be greater than zero" is contradictory with "sum should be b/w 0 and 1". Which is it?

What about
N = 3;
Population = rand(20,N)/N

Why do you say that? Just look at
theRowSums = sum(Population, 2)
and you'll see that none of the 20 rows has a sum greater than 1.
But you know, we really don't know what you want because you've said three different things!:
- "sum of each individual row should not be greater than zero"
- "sum should be b/w 0 and 1"
- "the sum exactly equal to 1 for each individual row."
There are three totally different things. Please, which one is it? Pick one and stick with it - don't give us a fourth definition.
