Scipy-like functionality in Java / Scala? [closed]

Question

I'm trying to port some Python code to Scala. It makes heavy use of Numpy and Scipy. While I've found a number of dense matrix / linear algebra libraries that will do as an adequate (but not superb) replacement for NumPy, I've not really found anything that provides the functionality I use in SciPy. In particular, I'm looking for a libraries that support sparse partial eigendecompositions (like SciPy's wrapping of arpack), and then libraries for some simple things that SciPy provides (e.g. histograms).

There have been a few similar questions already on this topic:

1. Java/Scala library for algebra, mathematics
2. Java / Scala math library with elliptic integrals and bessel functions?
3. Clojure or Scala for bioinformatics/biostatistics/medical research
