And what exactly are the results you are getting? On Fri, Feb 14, 2014 at 6:07 PM, Patrick Meyer wrote: > Hi, > > > > I am using the SingularValueDecomposition class with a matrix but it gives > me a different result than R. My knowledge of SVD is limited, so any advice > is welcomed. > > > >

[math] trouble with SingularValueDecomposition

Hi, I am using the SingularValueDecomposition class with a matrix but it gives me a different result than R. My knowledge of SVD is limited, so any advice is welcomed. Here's the method in Java public void svdTest(){ double[][] x = { {1.0, -0.05307180786272

[site] tags in developer checkout URL

Hello, I noticed that the published site of [VFS] has a example developer URL for SVN which contains the tag. This might be OK for a read only URL, but at least for the Developer URL I would rather document to check out trunk. If I understood it correctly thats a common problem with SVN. I notice

Re: [VFS] trailing space cleanup (was: svn commit: r1568471 - /commons/proper/vfs/trunk/pom.xml)

Because eyes are always on the code (thank you very much commit mailing list), people want to know the real differences between the files. It's extremely difficult to know what a developer did if a commit to fix something also includes cosmetic fixes. Separate the two out always and let the commit

Re: [VFS] trailing space cleanup (was: svn commit: r1568471 - /commons/proper/vfs/trunk/pom.xml)

I think you have too look at it from the POV of people who are going to look at the commit logs and emails to see the diffs. For me, I think it makes sense, to separate the meat of an implementation or fix from cosmetic changes. Sometimes it can be too much of a pain to separate the two, so this i

[VFS] trailing space cleanup (was: svn commit: r1568471 - /commons/proper/vfs/trunk/pom.xml)

Hello, quick question, while doing my first commit I noticed that Eclipse wanted to clean up a number of trailing blanks in that POM file. I decided to not commit those unrelated changes. What is your preference - should I do an additional cleanup commit, leave the blanks untouched or accept a fe

Can we agree on what problems remain currently before Benedikt wastes time on this? AFAIK the remaining problems are: - Commons Weaver TM link above left menu has Maven artifactId embedded in the href. I haven't yet found where this is coming from; - source info pages for modules also use artifact
