Generating Problems
On the Mathematica website I saw a short webcast on using mathematica to generate practice problems. I tried to find more information on how to do that but all I could find was the quiz generator for the Mathematica Teacher edition. I have the student edition. Does anyone know how I can go about generating practice... 21 Jun 2010 02:35

Book?
I am new to mathematica and I am looking at a book to learn mathematica (in fact I have not yet mathematica but I am considering purchasing a home license). I would say no more than 300-400 pages that explain how the system works, basic of programming etc... Any thought? Olive ... 23 Jun 2010 02:59

Named patterns forbidden in Except?
David Bailey wrote: I guess the point is that you could never use the name - because in your example, if x took a value, Except would fail to match by definition! Well, this is not a valid argument: I´m not using an isolated Except in a transformation rule. According to the documentation, "Except[c] is a... 22 Jun 2010 07:10

Setting PageSize and PaperSize
Hi Math Group Why does Mathematica not save the Paper Size option? When I go through the sequence below I get the page and printing setup I want: File Printing Settings Page Setup Paper Size (set it to 11x17in) I then save the Notebook, close it, and then open it again. Only now, the Notebook has the in... 30 Jun 2010 02:10

Bar chart style with ListPlot
Hello, I'm working with some discrete probability functions and plotting them using ListPlot. Given the nature of the function, I believe its clearest to represent the values using bars rather than points. I know there's a BarChart function, but it isn't as easy to use (e.g. you can't just give it a list of ... 20 Jun 2010 04:49

color legend
Hello Group, I want to add a color grayscale (myColorFunction[x_]:=RGBColor[1-x,1-x,1-x]) legend this arrayplot, from min (white) to max (dark) values. ArrayPlot[Table[5./(1 + x^2 + y^2), {x, -5, 5}, {y, -5, 5}], Frame -> None] best regards, eric ... 21 Jun 2010 02:35

Using Mathematica for Electrophysiology Data
Thanks Sjoerd! This works very well. I was indeed hoping to return the binning method as well, but this is not so important. The fitting is no problem now that I can build a frequency table from the histogram data. (And, yes, I always want to put an uppercase "L" in "NonlinearModelFit"!) To sum up: Data ... 19 Jun 2010 08:00

whats wrong with this code ?!
ok. I give up. I've been struggling with this the entire night. I have three functions: swap[..], split[..] and qksort[..]. The objective is to implement a recursive sort algorithm. I have tried to execute it on list={2,5,4,7,9,1};. But I keep getting the "Cannot take positions .. through .. in .." message. You... 23 Jun 2010 02:59

NotebookDirectory for package (.m) files?
Hi group, i would like to create an application package that included a data directory that can should be accessable for commands in the application. Of course I can hard-code the path in my .m file but what is the proposed way to do this in case I would like to provide the package to other users which might ins... 23 Jun 2010 02:59

Workbench fails to build documentation
Hi group, after some frustrating fights with Workbench 2 and quite unconclusive emails with Wolfram Support I would like to ask if anybody else is having similar problems or even any ideas how to solve them. The problem is: Workbench completely fails to build any documemntation file. No matter which. I tried t... 23 Jun 2010 02:59
