multidimensional array - Java equivalent for the Numpy multi-dimensional object

Question

After using it for a while, I really like the Numpy multi-dimensional array. It's helpful to write algorithms with a concise yet readable and fairly general code. I wish to have the same thing in Java. Before coding a multi-dimensional array with a Numpy-like API myself, is there such a thing already ?

[PS] I searched a bit, did not see

Answer 1

The OP is from 2011. So as of end of 2015 I would like mention that there is a new kid in town which claims to be numpy for java -> nd4j. The nice thing is that nd4j is an abstraction layer on top of different libraries like blas. Depending on the size of your matrices there are underlying implementations twice as fast as numpy or jblas. And your code is real platform independent.
