Subject [jira] [Commented] (MATH-851) Add convolution
Date Tue, 21 Aug 2012 14:56:38 GMT

Clemens Novak commented on MATH-851:
------------------------------------

Thanks a lot for your comments and suggestions. I hope I got the issues mentioned above and
the source code formatting right. As a side note: I have seen there is a wiki - Would it make
sense to collect these general guidelines there? Currently, this information seems to be spread
across several tickets... I'd volunteer for that :-)

I assume that there will be a performance loss when using RealVector; on the other hand, RealVector
provides many convenience functions a bare metal double[] array lacks (I have a rather strong
Matlab/Octave background where everything is vector-based). However, I think this is a architectural
decision (a performance comparison between RealVector & double[] might come in handy here)...

> I created a function performing (one-dimensional) convolution. Currently, the function
is in a class called Filter, but I am not sure whether this is the appropriate place for it(?).
