To amplify and extend the question - would also like to know the same info 
where bigdecimal is involved.

Thanks.

Subject: [math] noob; performance metrics?


sorry if this has been asked many times before. (maybe this can be added to 
the FAQ?)

has anyone done any bench marking?

The idea of having a math package that is implemented pure java is very 
attractive. My experience with machine learning is that java is very slow. 
To go fast you need to take advantage of assembler or libraries written in 
fortran or C. For example http://jblas.org/ <http://jblas.org/>


Kind Regards

Andy
