object bincount extends UFunc

A breeze.generic.UFunc for counting bins.

If passed a traversable object full of Int's, provided those ints are larger than 0, it will return an array of the bin counts. E.g.: bincount(DenseVector[Int](0,1,2,3,1,3,3,3)) == DenseVector[Int](1,2,1,4)

One can also call this on two dense vectors - the second will be treated as an array of weights. E.g.: val x = DenseVector[Int](0,1,2,3,1) val weights = DenseVector[Double](1.0,2.0,1.0,7.0,1.0) result is bincount(x, weights) == DenseVector[Double](1.0,3.0,1,7.0)

    A breeze.generic.UFunc for counting bins.

    This differs from bincount in that the result it returns is a SparseVector. The internal implementation of this could probably be significantly sped up by avoiding the use of counter. Then again, in sparse situations it's still a lot faster than using bincount.
