- 1. how to read this data file in mathematica?

hi, I have a data file with its first line of data as follows: 8.1000E-01 1.6090E+03 8.3000E-01 1.5490E+03 8.5000E-01 1.5810E+03 8.7000E-01 1.5120E+03 8.9000E-01 1.5650E+03 9.1000E-01 1.5680E+03 9.3000E-01 1.5450E+03 9.5000E-01 1.6570E+03 9.7000E-01 1.5900E+03 9.9000E-01 1.5750E+03 Now I want to read it in mathematica and transform it to satisfy the data format as below. {{8.1000E-01 1.6090E+03}, {8.3000E-01 1.5490E+03}, {8.5000E-01 1.5810E+03}} what should i do? thx! - 2. Shared Functions

Hi All, I have a notebook with some functions that I want to use in some other notebook. Is possible to "include" a Mathematica notebook into another one? Or, how I can create a "shared" function (in Mathematica Language, not in C or Java...) and reuse it? Thanks for help, Massimo Sironi - 3. Show Factor

Is there any way to have Mathematica show the steps for the Factor function? According to what I read, there is supposed to be a ShowExpand function. (However, it doesn't work on my version 5.0 -- perhaps it's in a package?) So I assume there must be a way to show the steps for the Factor function. Can anyone help me here? Andrea - 4. How does one export a DXF file with PolygonsOnly set to true?

I am using Mathematica version 4.2 The command to export a DXF file has changed from my version 4 documentation to this command and syntax.. Export["filename", graphic, "DXF"] The old documentation though regarding the old DXF making method mentions a option of "PolygonsOnly ->True". I added this option , via a comma and the option and it does not work. How can I export a DXF file with PolygonsOnly being set to true? What is the correct syntax? - 5. Streaming input (with Linux)

Hello everyone, I have build up a very simple script in Mathematica, taking tree real parameters in input and giving as output a real number. At the moment my script read an input file containing the tree parameters, but it would be better for me to tell the script the parameters with a direct command line instruction. Does anyone knows how to do something like > math < my_script.m par1 par2 par3 And how to handle the parameters inside the script ?

Hi Dan, there is something wrong with your slash. You may convince yourself by typing: Divide[a,b] instead of a/b. Somhow mathematica gets another character than slash. I assume your are using a non english keyboard. Check your international settings. hope this helps, Daniel

what is wrong is the look ov the slash. But it is unterstood like a slash. The small square is the straight and short line. And the result when I print (to my printer :) ) is good. I use the Kubuntu 6.04 system.

This is just a guess, but make sure that Mathematica has access to its fonts: http://www.**--****.com/

Hi Dan, I have exactly the same problem, however I am working under Gentoo Linux. I had a look under Edit->Preferences->Advanced. I opened the Option Inspector and looked at Formatting Options->Font Options- "Bitmap", "Outline" and "NoTrueType". If I choose the latter then I can see the "/@#" characters again. However the overall quality feels slightly worse. Could you please check whether that works for you as well? /Andreas

You're right, it works well. I had a discussion mith Mathematica Support. I will report your method, and come back with their answer. Thank's a lot ! Daniel.

Hi Dan, I finally found out what was the problem on my system (Gentoo). I had still the Gentoo package for the mathematica 5.2 fonts installed (media-fonts/mathematica-fonts). I had removed their path from the xorg.conf and added the location of the mathematica 6 fonts their. However in /etc/fonts/fonts.conf still the path of the mathematica 5.2 was present. Adding the mathematica 6 font path to the /etc/fonts/ local.conf did not help. However, when I finally completely uninstalled the mathematics 5.2 fonts everything works fine. I am not sure that this helps you, but you might check the above configuration files as well. /Andreas
