CalcLink tutorial screencasts on YouTube Yesterday I have made four screencasts about my commercial product CalcLink and uploaded to YouTube. Part 1: Use from the Mathematica front-end http://www.youtube.com/watch?v=gR7xan0zncg Part 2: Use from the Spreadsheet http://www.youtube.com/watch?v=HXpv550Oh6Q Part 3: Graphics Capabilities and CalcPad htt... 23 Mar 2010 05:37
ListContourPlot3D Hi, I have data in the format data5= { {x1,y1,z1,f1}, {x2,y2,z2,f2},... }. I would like to see 3D contour lines. I use the command: ListContourPlot3D[data5, PlotRange -> All, AxesLabel -> {"\[Beta]", "\[Omega]", "Vo"}, Contours -> {4000}] and get an empty box with the axes running from -1 to1. Any help ... 24 Mar 2010 06:34
"Quick and dirty" Solve[] Hello all, In order to found an upper bound for a numerical integration, I would like to "solve" something like Solve[f[x]<1*^-10,x] but in a quick and dirty way; let me explain : - dirty, in the sense that I would be happy to find an x for which f[x] is say between 1*^-9 and 1*^-11 or so - quick in the sense t... 25 Mar 2010 05:45
Looking to solve PDE on an annulus? I'm trying to solve a PDE on an annulus with Mathematica (or another system, but its not as simple). Is there a way to do this through NDSolve? Anyone know how I can do this? ... 24 Mar 2010 06:34
number representation Hi, Mathematicas default behavior with representing floating point numbers seems to be that numbers greater or equal to 10^-5 are shown without and numbers smaller than 10^-5 are shown with a sort of Scientific notation, i.e. floatingpointnumber x 10^-n. So for example the input 0.00001 delivers 0.00001, but th... 22 Mar 2010 08:15
Sorting Filenames into HTML Coding I have a web page HTML coding problem which I'm trying to use Mathematica's file and string functions to solve for me. I've created a text file, in DOS of 695 file names which I've "imported" (via the "Lines" option) and need to manipulate each into HTML table data code like the following: For example, given a... 28 Mar 2010 05:43
Managing packages in the workbench Hello, the thread http://groups.google.de/group/comp.soft-sys.math.mathematica/browse_thread/thread/a67d924983da8c34# has several good recommendations for the transition to the workbench, thanks to John Fultz, Albert Retey, Adam Berry, David Park and others. Nevertheless, I was not successful to get my packages i... 4 Apr 2010 08:14

Passing options to functions / overriding default Hi Leo, For one thing, DeleteDuplicates is not strictly necessary since only the first rule with the same l.h.s. applies. More generally, though, creating a wrapper only to redefine some options seems a bit of an overkill. Logically, someone who sees <foo> in your code (may be yourself a few weeks later) will ... 21 Mar 2010 03:49
Need larger window for Manipulate Slider Control Would a value label at the right side of the slider work for you? Manipulate[x, {x, 0, 10^6, Appearance -> "Labeled"}] does that.
