 May19 comment Cannot solve system of linear equation sums? any ideas for a workaround? Mar7 comment Draw only the top of the boundary of a function in Plot3d Uhm that's Sec[x], not 1-x . also can I just put the function in to extend this for any function, e.g. a complication combination of x's and y's. ? Mar6 comment Draw only the top of the boundary of a function in Plot3d ...... I just want to change which points are colored Green... right now all of the borders of the functions are colored Green. I don't think? RegionPlot is relevant Sep13 comment @Verbeia: YES :D. uhhhhh anything you suggest - i can start doing ;) Apr16 comment How to convert a 2D image into a 3D graphics? Well, basically I wanted/want to do edge recognition and then convert it into a 3d object in autocad though I haven't tried the Raster Design solution yet. Export[path.dxf,EdgeDetect[Import[path.jpeg]]] is what I'm looking at. Apr13 comment How can I visualize features found in an image? @rcollyer nice name haha :) Apr13 comment Torn edge paper effect for images Wow o_o this is amazing :) Apr10 comment Creating legends for plots with multiple lines? Anyway to increase the size of the Legend font using this? Apr10 comment Mapping and Interpolation @BrettChampion in this scale that is exactly what I'm looking for! thanks. Is it possible to use mappings of other orders, ex. a normal distribution or a quadratic mapping? This being a linear mapping. Apr10 comment Mapping and Interpolation what would make the question more clear? An example would be reading in a sensor that gives values on [0,256] and using those to operate say a servo which accepts values on [0,10]. Apr10 comment How to Map a subset of list elements to a function? @kguler I already upvoted it :). I like the timings chart. How did you do that? Apr10 comment How to Map a subset of list elements to a function? why is it f[#[[1]], #[[2]]] and not just f[#1,#2]? Apr8 comment Combining heads of lists so that you can create a nested list from two sublists Interesting I did not know that. Thanks :D. About the terminology I have no clue whether you are or not, I was just wondering if there was some notation/convention I did not know about. Thanks! Apr8 comment Combining heads of lists so that you can create a nested list from two sublists pardon me but ... canonical? What do you mean in that sense? Apr8 comment Map and Apply a function on a nested list how do you do log arguments though, ex. Log[1,2] Apr7 comment Creating legends for plots with multiple lines? thank you, I believe that should work! Apr7 comment Creating legends for plots with multiple lines? I would like the legend to say that [Line of Color A] = $Log_{a} x$ and the next [Line of Color B] = $Log_{b} x$ etc. where $a,b,c ...$ is specified by that Table iteration Apr7 comment Map and Apply a function on a nested list thanks! I'll try Apr7 comment Computing and plotting a spectrogram in Mathematica Ok. Thanks, I haven't seen a function in brackets before so I was uncertain where to look, as things such as @ are hard to find. Addtionally, what is ~Join~ ? I saw it on an answer somewhere. Apr7 comment Computing and plotting a spectrogram in Mathematica how about a 3d surface spectrogram? en.wikipedia.org/wiki/File:Spectrogram.png additionally, what is [Transpose]
