Row unity in matrix

Hi there,

I've created a random 9 times matrix using the command:

P = rand(9,9)

How do I make sure that the rows in each of the matrix are equal to one when added?

Any help will be appreciated!

Thanks

P_norm = P./sum(P,2);

>> P = rand(9);
>> NP = normalize(P, 2, 'norm', 1);
>> sum(NP, 2)

ans =

                         1
                         1
                         1
                         1
                         1
                         1
                         1
                         1
