generating random values with condition

Hi all

how to generate 12 random values, each number can be in the range from 0.01 to 1 but the summation of each successive 4 numbers must be equal to 1.

This is quirky enough that it sounds very much like homework. And I'm sure that you can't ethically turn in our code as your own, so read this link, and read the documentation on rand(). And realize that you can divide and multiply sets of 4 numbers to get new, scaled numbers.

You could use this FEX submission by Roger Stafford for each 4 number block:
