 Apr 2 answered How to find the limit of a function of two variables Mar 21 comment Why does ImageFilter fail with radius 1, but works with radius 2? The 76 evaluations might be explained by some kind of parallel (nonatomic) writing operations in the variable n during filter evaluation. Mar 18 revised Total and partial derivatives deleted 1 character in body Mar 18 answered Total and partial derivatives Mar 4 awarded Good Question Dec 15 awarded Yearling Dec 7 comment Insert a string and add 0.5 in the last element in every list after I strongly encourage you to learn the basics about "list manipulation". It's one of the most important things when working with mathematica. Nov 10 comment Mathematica will not detect NVIDIA Titan X for CUDA functions @DiegoAlonsoCortez: There might be a way to get the MSVC compiler from visual studio to work with Mathematica (I imagine I read about that somewhere), but out of the box Mathematica only supports VS 2013 or older versions. Oct 22 comment A method to draw a surface around a set of regularly spaced points @Rahul: I am aware of the paper, but am currently just interested in "onboard methods" supplied by mathematica directly. I also do think that the results from the paper tend to "oversmoothing", but it might be still one of the better techniques out there to use in my case. Oct 22 comment A method to draw a surface around a set of regularly spaced points @SjoerdC.deVries: Definitely not, I think we are both past attending university lectures :). Oct 21 comment A method to draw a surface around a set of regularly spaced points Oh, I literally posted the same question just a few minutes ago. I am stuck with ListContourPlot3D right now, but there might be some options I do not know of for different "intepolation" methods. Oct 21 asked best way of plotting 3D surface from a binary voxel representation in Mathematica Oct 19 comment Why doesn't Simplify use my own TransformationFunction? Makes sense that it tries to minimize ComplexityFunction. For some reason I was naive enough to think that manually supplied TransformationFunctions have absolute priority.

Aug 16 comment How can I capture a rectangular area from an image? @JunhoLee: I get that, I just meant to think about what exactly separates one element you want from another (it seems to me that almost white lines in the image might already do the trick) and then detect those characteristic elements automatically. Afterwards it is just extraction with ImageTake and proper coordinates from the detection procedure mentioned before. Aug 16 comment How can I capture a rectangular area from an image? I would definitely analyse the image for whitespace between the different regions you want to extract or find some other characteristic elements in your image to look out for. Once those are found it should be a simple ImageTake on the remaining bounding box. Aug 16 comment How can I capture a rectangular area from an image? Could you please elaborate this problem a little bit further. Right now I cannot really see what the characteristic elements that make up your regions are because your desired output is from a different page than the input example. Jul 26 comment An equivalent to Condition that I can use anonymously when string pattern matching @Mr.Wizard: Thanks for the great job you are doing on this forum! (sorry for ignoring the no thank you rule ;)) Jul 26 comment Maximize[Cos[x - 1], x] is not evaluated Well, it seems to be fixed in Mathematica 10.2 (running on OS X here).
