 'in core' as in whole matrix loaded into memory ? I am looking for 'distributed' matrix inverse
because the matrix is very big (2 million x 2m), and it is a Complex Double matrix.
btw, which API is for the in-core inverse ? thanks,

 Do you mean in core matrix inversion? It is supported via solve. Actually
it is supported both in Java and Scala.
