Re: [Math] Serializable (again)

Hi In my opinion for more advanced uses it makes sense to use tools like Googles protocol-buffers for serialization: http://developers.google.com/protocol-buffers/docs/javatutorial The main advantage is, that you can share data with applications written in C++ or Python. -- Axel Kramer

Re: [Math] Proposal for a set of interoperable interfaces for mathematical structures

To extend JAS with the commons-math methods the easiest way is to extend the edu.jas.structure.AbelianGroupElem like this: public interface AbelianGroupElem> extends Element, FieldElement and add the methods: add() and getField() in all derived classes. But there's already an add() meth

etEigenvector(0); assertEquals(rv0.toString(), "{(NaN); (NaN); (NaN)}"); } but I'm getting only {(NaN); (NaN); (NaN)} as a result vector. Is this intentionally (because of numerical inaccuracy?) or am I doing something wrong in using EigenDecompositionImpl? -- Axel Kramer
