             Summary: Add rand() operator to math-scala
                 Key: MAHOUT-1599
                 URL: https://issues.apache.org/jira/browse/MAHOUT-1599
             Project: Mahout
          Issue Type: Improvement
          Components: Math
    Affects Versions: 0.9
            Reporter: Felix Schüler
            Priority: Trivial
         Attachments: MAHOUT-1599.patch

I was looking at the scala-math operators and missed a rand(m, n) operator that generates a m x n matrix filled with random numbers.

I wanted random numbers from a uniform distribution over a specific interval so I implemented a simple uniform random number generator.

the rand(m, n, r) function takes any AbstractSamplerFunction and fills the matrix entries with the numbers generated by its sample() method.
