Thomas Jungblut commented on HAMA-524:
--------------------------------------
bq. Please try to implement your own classes.
Would be cool to have some neat math classes for vectors and matrices though.
You can have a look at https://github.com/thomasjungblut/tjungblut-math
It is inspired by the class design of mahout-math.
Here is the Writable implementation of the vectors:
https://github.com/thomasjungblut/thomasjungblut-common/blob/master/src/de/jungblut/clustering/model/VectorWritable.java
Just in case you need them, they are Apache2 considered, so you can just copy
and paste to our project. But it would be cool if you add testcases.
