Thanks for the lines, I think I wasn't 100% getting that `Rand.randInt(32)` gives out a `Rand[Int]` and can be fed into `Matrix.rand()`. I think I do appreciate now the Scala-y elegance, especially compared to the numpy or Matlab syntax for constructing more involved random matrices.

_(I wonder if the "different kinds of vectors/matrices concern could be allayed, given that random construction is only really needed for DenseVector/DenseMatrix? I totally see what you mean now for `zeros` etc.)_


I see it now mostly as a documentation issue, I will add this rand construction stuff to the wiki page on how to construct Matrices.
