Did you know that we took Mathematica to Maker Faire this year? Read more about it: http://blog.wolfram.com/2009/06/17/makin g-the-most-of-mathematica-at-maker-faire /

Have you ever wanted to do that in Mathematica? http://blog.wolfram.com/2009/05/28/how-d o-you-do-that-in-mathematica/

thanks for that info. newbie here.. i am looking forward submitting my own demonstrations when i finally master mathematica. there's a seminar i attended last night and i couldn't catch up. so i think it's better off study it first myself.


Wolfram Mathematica James: Those are cool graphics! Thanks!


Wolfram Mathematica Gabriella: What kind of index do you mean?
Wolfram Mathematica at 10:17am May 5
Gabriella: Are you using Default Stylesheet? If so, you will need to highlight those cells and go to Format->Style->and select ItemNumbered. If this isn't the issue, please send a sample of your notebook to support@wolfram.com and Technical Support will be able to help you.

Wolfram Mathematica James: I checked with Technical Support and they said you can get around the issue by setting WorkingPrecision for the Plot: Plot[(1 + 3/x + 5/(x2))^x, {x, 10, 1010}, WorkingPrecision -> 15] Hope this works! Thanks!


Wolfram Mathematica Armin: Technical Support said that they emailed you an answer. I just wanted to follow up and see if it was what you needed. Thanks!


Wolfram Mathematica Shaun David: We are looking forward to releasing Mathematica Home Edition internationally, but we do not have a strict time line for it. When it's available for more countries, we will post a note on our wall. Stay tuned!


Wolfram Mathematica Robert: Technical Support and a couple of our developers have looked into the SVG issues you are experiencing. The team will add it to their list of items to investigate as soon as possible. Thank you!


Wolfram Mathematica Charles: With the changes to Facebook, the questions now appear on the "Just Fans" part of the Wall and the answers tend to go to the "Wolfram Mathematica" part of the wall. Thanks!


Wolfram Mathematica
Jeff: Technical Support says that the problem you describe has been fixed in 7.0.1. In[107]:= fun[i_]:=Sum[Subscript[a,n][t]+b[t],{n,1 ,i}] In[108]:= fun[3] Out[108]= 3 b[t]+Subscript[a, 1][t]+Subscript[a, 2][t]+Subscript[a, 3][t] In[109]:= fun[x]/.x->3 Out[109]= 3 b[t]+Subscript[a, 1][t]+Subscript[a, 2][t]+Subscript[a, 3][t] In[111]:= $Version Out[111]= 7.0 for Mac OS X x86 (64-bit) (February 19, 2009)


Wolfram Mathematica
Wayne: To avoid the common rounding issues with computers, Technical Support suggests that you purposely clip the results (Floor[Round[ 100*{0.29, 0.58}, 0.01]] ) or use integers (Floor[100*{29/100, 58/100}]). You can find more information on Machine Precision numbers at http://reference.wolfram.com/mathematica /tutorial/MachinePrecisionNumbers.html. Hope that helps!


Wolfram Mathematica James: Import is a very powerful function that supports a variety of file formats, including HTML. Please check it out at www.reference.wolfram.com.

Bad link. No www in the url. It should be just http://reference.wolfram.c om
I must say the reference center has some good examples for each and I think everyone of the commands in Mathematica.
I don't think there is anything I have not been able to find.

Wolfram Mathematica Ryan: AspectRatio or maybe ImageSize option might help? Check the Documentation Center's AspectRatio and ParametricPlot under Options> AspectRatio. Thanks!


Wolfram Mathematica Happy Pi Day!


Wolfram Mathematica Afshin: Ah. Well, if no one posts a good answer for you here, feel free to email support@wolfram.com for more help. Hope it comes together for you soon. Thanks!


Wolfram Mathematica
is excited about the post at http://blog.wolfram.com/2009/03/05/wolfr amalpha-is-coming/


Wolfram Mathematica
Afshin: Thanks for the note. Technical Support says you might want to try the function called GraphPlot:
http://reference.wolfram.com/mathematica /ref/GraphPlot.html
This function can accept adjacency matrix and plot it. For more information about drawing graph, please refer the following tutorial page:
http://reference.wolfram.com/mathematica /tutorial/GraphDrawingOverview.html
Also there are many demonstration related networks (you might be interested in) in Wolfram Demonstration site:
http://demonstrations.wolfram.com/search .html?query=network&submit.x=0&subm
it.y=0
Thank you!


Wolfram Mathematica Boris: We will look into a forum. Thanks for the great idea!


Wolfram Mathematica
Afshin: I checked with Technical Support again for you. Here's the answer I got back:
There might be various ways to do this. I will show two examples here:
First one is by using Apply,Map, and And:
myFunc2[myList_, subList_] :=
If[Apply[And, MemberQ[myList, #] & /@ subList], True, False]
The second one is by using Complement (it's shorter):
myFunc3[myList_, subList_] :=
If[Complement[subList, myList] == {}, True, False]
In[34]:= myFunc[{a,a,a,b,b},{a,d}]
Out[34]= False
In[35]:= myFunc2[{a,a,a,b,b},{a,d}]
Out[35]= False
In[36]:= myFunc3[{a,a,a,b,b},{a,d}]
Out[36]= False
In[37]:= myFunc[{a,a,a,b,b},{a,a}]
Out[37]= True
In[38]:= myFunc2[{a,a,a,b,b},{a,a}]
Out[38]= True
In[39]:= myFunc3[{a,a,a,b,b},{a,a}]
Out[39]= True
Hope this helps. Please let me know if you need anything else. Thanks!
