I have placed both these directories in the appropriate place on the path but trying to load the packages << Utiltities`Plot` i ge... 1 Jun 2010 05:24
Draw tree with equal branch lengths Hi, I am trying to draw a tree with TreePlot. I would like the branches to have equal lengths but don't see how to do it in a simple way. Any suggestions? Sample Code: TreePlot[{i1 -> 1, i1 -> 2, i1 -> i2, i2 -> 3, i2 -> 4}, Center, VertexLabeling -> True] The tree comes out with unequal lengths. And ... 1 Jun 2010 05:24
Lists: how to? Hello: I have this line subs3 = Subsets[Range[numbr], {3}] which for numbr=7 gives subs3= {{1,2,3}, {1,2,4}, {1,2,5}, {1,2,6}, {1,2,7}, {1,3,4}, {1,3,5}, {1,3,6}, {1,3,7}, {1,4,5}, {1,4,6}, {1,4,7}, {1,5,6}, {1,5,7}, {1,6,7}, {2,3,4}, {2,3,5}, {2,3,6}, {2,3,7}, {2,4,5}, {2,4,6}, {2,4,7}, {2,5,6}, {2,5... 31 May 2010 00:05
Q about ParametricPlot3D I would appreciate advice on these questions: 1. Why do I need Table in this expression: ParametricPlot3D[Table[{(Cos[ang] xb + Sin[ang] yb)*radb + cenb, (Cos[ang] xa + Sin[ang] ya)*rada + cena}^], {ang, 0, 2\[Pi]}, PlotStyle -> {Blue, Thickness[.01]}] 2. In the no-Table form that I expected to wor... 29 May 2010 04:56
exporting EPS files with Illustrator compatible fonts I've seen multiple messages about exporting EPS files from mathematica with fonts that cannot be seen in Adobe Illustrator but nothing seems to fix this issue completely or at least across multiple versions of mathematica. (I'm using Mathematica 7 on Win7 and illustrator CS3). Basically I want the Greek letters ... 30 May 2010 07:52
Corruption of formulas after cut-and-paste A warning to people who are trying to write packages: Cut and paste may corrupt formulas, especially if they use complicated typesetting. (My version: Mathematica 7.0.1.0, Linux x86-64) Example: Open a notebook in Mathematica (e.g., a .nb file) and type -1 f[x_] := x -----; ... 28 May 2010 08:13
Why? Hello, Consider the following: In[1]:= N[1.000000000000000000000001 - 1, 60] Out[1]= 0.*10^-24 I can not understand why this happens. Can anyone explain the reason? What is about "arbitrary precision arithmetics"? ... 28 Jun 2010 03:01
hexagon tiling demonstration Hello. I'm trying to create a basic demonstration to generate a hexagon tiling. My code below generates a single row of tiled hexagons, running from quadrant 3 into quadrant 1. But this is essentially only one dimension of hexagons; now I'd like to fill "above" and "below" this one row, and I'm not sure how to a... 28 May 2010 08:13 |
