Toolbar
Dear All, Is it just me or others as well would appreciate a toolbar in Mathematica? I've missed it at the first time I've encountered Mathematica 4, but, since then, I've simply got used to the routine to kill the kernel or delete all output using key-combinations. I wonder why there is no useful toolbar at all... 23 Dec 2009 13:42

Curve-fitting,
Dear Mohamed, Thank you for your generous contribution to the Mathematica body of work available for all to benefit from. I have downloaded your notebook and read briefly the PDF and tried the notebook with Mathematica V7.0.1 and Mathematica V5.2. There are a few compatibility issues with both my versions whic... 14 Dec 2009 00:09

Having problems finding skeleton of a binary image using Lantuejoul's
I am trying to find the skeletal subsets Skel(S;n) = (S (erosion) nE) - (S (erosion) nE) (open) E) for a simple rectangle. Skel[n] is returning a completely black image for n=0,1,2,3,... I think that I should be getting the classic dog bone shaped skeleton like you see with ImageAdjust[DistanceTransform[s]]. I ... 12 Dec 2009 06:58

Animation with Sound in Mathematica?
Can anyone give an example of a true multimedia-like "music video" created exclusively in Mathematica 7? I have not worked with animation very often, and although I understand how to use the related functions, I haven't found a way to "sync" them to a/an audio (Play or SoundNote generated) track(s). An example of... 16 Dec 2009 06:51

CVS Install on Windows XP for Workbench
We are attempting to install and configure CVS so it can be used by the Wolfram Workbench CVS client. We have multiple Windows XP computers all accessing a single shared drive. We have installed CVS on the shared drive. We can run the server in "local access method" from a command line in a DOS window on all system... 11 Dec 2009 06:56

NDSolve: Affecting dependent variable during solution?
Hi, I'm trying to solve a system of ODEs in Mathematica where the immediate value of one of the dependent variables changes during the course of the evaluation. For example, the system A -> B at a rate of 1 s^-1, and B -> A at a rate of 1 s^-1, A[0] = 1, B[0] = 0, is easily set up: k1 = 1; km1 = 1; sol = NDSolve[... 10 Dec 2009 05:44

would like to compute a tensor derivative of a function and
<anonymous> wrote: Hi, you should explain what you exactly mean by "tensorial derivative". If you really mean the covariant derivative then you did not give enough information. But maybe you mean the ordinary derivative. E.g.: D[ W[C[x,y,z]], x]. Here we have the problem that Mathematica has no ... 15 Dec 2009 07:51

Manipulate a NDSolve equation is it possible
Can the following be made interactive? I would like my students to see there results quickly when changing certain values such as the resistance and capacitance.
