How to dynamically build a list of rules Hi there! I need a somewhat larger list of substitution rules along the line of subs = { name1 -> SomeFunction[name1], name2 -> SomeFunction[name2], ... , nameN -> SomeFunction[nameN]} Obviously typing that by hand can become a little annoying. So I would like to have that list created dynamically, via Table... 20 Apr 2010 15:52
Equation problem I just started using Mathematica and have no idea how to do the following... I have the starting equation: y=((1+sqrt(5.71e8/x))*x)/6.38e9 What I want is to obtain x=a+b*y, where a and b are parameters. Is this possible in Mathematica? ... 20 Apr 2010 15:53
Two dimensional Splines After having sailed into Mathgroup and Help, we still face the following problem. Suppose we have a set of 3D points (x_i, y_j, f[x_i,y_j]) with i=1...N, j=1...M and we need to a) interpolate the surface by **using** <<Splines` and SplineFit[...,cubic] a.1) plot the interpolating (spline) surface a.2)... 13 Apr 2010 22:54
Bug in Sum? In the following, A and Expand[A] give different answers after when summed (a finite geometric series.) The result of summing A is clearly wrong, since it is independent of the parameters r and s. Abhishek In[44]:= A = x^(i - n) (x^(i - n) (1 - r x^n) - s); A == Expand[A] // Simplify Out[45]= True In[46]... 20 Apr 2010 15:53
Using package functions in Manipulate/DynamicModule Hey. My objective is to deploy in a Mathematica Player file a document which has some interactive stuff, without any code visible. Ideally, it would be all in a single file but I can live with sending a .m package file too. So far so good. Inside a DynamicModule I used some functions from a .m file I had created... 17 Apr 2010 06:24
How to make style sheet with header I have been trying unsuccessfully to make a style sheet with a header. I am not talking about a header that appears when you print the notebook. I am talking about a header that is on the notebook itself. An example of what I am talking about is the "Confidential Report" style sheet that is available with Mat... 16 Apr 2010 06:09
Can you communicate about Mathematica? * Can you communicate about Mathematica? Wolfram Research continues to expand ... and we're looking for people to explore and explain applications of Mathematica in diverse areas. If you are enthusiastic about Mathematica and its applications, good at written communication, and savvy about understanding market ... 12 Apr 2010 23:39
Formatting GraphicsRow/column I can't find a way to format my output graphics/stuff in columns and rows without giving the same width/height to all items. For example, I have a thin graphic and a fat one and I want them one next to the other. In the documentation on GraphicsRow and GraphicsColumn says that's the "default" behaviour, but I can'... 18 Apr 2010 06:29
ListPlot with two horizontal axes I have data I would like to plot with two horizontal axes. I.e. signal magnitude as a function of wavelength and frequency. Is there a way to label the horizontal axis with two scales? (Note, freq is inversely proportional to wavelength.) Thanks! Eli. ... 13 Apr 2010 22:54
