label graph vertices
greetings, after having used for some time a very powerful program (Graphviz) for displaying the graph structures I'm working on, I decided to give it a try under Mathematica, since I use M. for many other related tasks. I started from DiscreteMath`GraphPlot`, but from what I can see everything is done using an ... 7 Apr 2007 04:20

Import of CSDF files
Hallo, I want to import CSDF files from PSpice. Is there any package out there that can do this job? I'm quite sure this has been done before, and I don't want to reinvent the wheel! Any help would be highly appreciated, I'm running version 4.2. Thank you Oliver Friedrich ... 12 Mar 2007 06:03

Kernel Crashing with NDSolve Command
Hi all i have this rather innocuous looking NDSolve command thats crashing the mathematica kernel, NDSolve[{y'[x]==Min[s[x]+Sin[x],Cos[x]-s[x]],y[0]==0,s[x]==x^2},{y,s},{x,0,3}] If i were to substitute s[x] in this equation with x^2 and then try solving, i get an answer, if i assign s[x] in advance and try s... 28 Feb 2007 05:05

how to configure a remote kernel
Hi, I have problems to configure a remote kernel. The local machine is WinSP/i386, the remote is SuSe10.1/x86_64. Both machines are in the same LAN, no firewalls, no routers. As a Shell Command I have: ssh 192.168.87.99 -l tsariysk 'math -mathlink -LinkMode Connect -LinkProtocol TCPIP -LinkName "`link... 27 Jan 2007 05:47

NDSolve -- initial conditions
Hello MathGroup, For computation of initial conditions NDSolve uses somehow the simulation time. For example: ==== equ = {D[x1[t], t] == -10^5 * x1[t], x1[0] == 1}; NDSolve[equ, x1[t], {t, 0, 50}, "SolveDelayed" -> True]; NDSolve[equ, x1[t], {t, 0, 100}, "SolveDelayed" -> True]; --- The first NDSolve... 29 Jan 2007 04:28

Databaselink and MySQL
I am trying to connect to a MySQL database using Mathematica's databaselink library. I can connect to the test databases provided with Mathematica (which are HSQL databases), and my MySQL databases work well on their own, but when I try to connect to the MySQL database from Mathematica, I get errors. My conn... 24 Jan 2007 05:34
