Hello

I want to get N random numbers that the sum of them is a value.

For example, let's suppose I want 5 random numbers that their sum is 1

Then, a valid possibility is:

0.2 0.2 0.2 0.2 0.2

Other possibility is:

0.8 0.1 0.03 0.03 0.04

And so on. I need this for the creation of the matrix of belongings of the Fuzzy C-means.
