Ingolf Dahl's Mathematica stuff

Tetration

Addition, multiplication, exponentiation, ... What comes next? Tetration, or PowerTower in the language of Mathematica. Here is a notebook with the routines for extending the exponent to real positive values: http://web.telia.com/~u31815170/Mathematica/PowerTower.nb. The current version is created 2006-12-21, with added theory and graphs and changed routines. If you do not have Mathematica available, you might download a notebook reader from http://www.wolfram.com/products/mathreader/ .

More to come...

DivideTriangle

A routine to split a triangle, or a list of triangles, into small triangles with all sides less than d: http://web.telia.com/~u31815170/Mathematica/DivideTriangle.nb.

TaggedCells Package (still beta...)

By default Mathematica notebooks are organized linearly, with output cells following corresponding input cells. Sometimes it is useful to have larger freedom in how to write and read. We maybe want to rewrite the same cell several times, for example if we want a status window to monitor an on-going process. Or we might want to write to the same cell from several positions in a notebook. Or we might want to collect the results from a complicated calculation in a nice formatted report. Mathematica provides a mechanism to "tag" cells with names. Or maybe create a game? This package provides routines to utilize this in a convenient way.
Some routines is also provided in this package to enter input to Mathematica programs in some different ways plus a few utilities. The functions in the package have full option and help support.

• The possibility to make 3D animations where the viewpoint can be changed dynamically during executions.
• The possibility to get Graphics coordinates from inside a program loop
• A rudimentary Mathematica-Aided drawing program. Yes, fully inside a Mathematica notebook, no Java stuff here. Although primitive, you might use it to paste your Mathematica formulas into your own Mathematica graphics.
• FormOptionSequence is an modification of Utilities`FilterOptions` with enhanced functionality.

Available commands and options: AnimateToClosedGroup, AppendToTaggedCell, DeleteTaggedCell, EvaluateTaggedCell, EvaluateWithTaggedCellButton, ExpressionCell, ExpressionToTaggedCell, FilterOptionList, FormOptionSequence, GraphicBoxDataCell, GraphicsCell, GraphicsCellGroup, InterruptButton, InterruptButtonCell, InterruptWithTaggedCellButton, InvisibleNotebook, NotebookReadTaggedCell, OptionalNotebookOpen, PauseFunction, PrintToTaggedCell, ReadCellInformation, ReadCellInformationTaggedCell, ReadCellSerialNumbers, ReadCellSerialNumberTaggedCell, ReadCursorPosition, ReadMousePad, ReadOptionTaggedCell, ReadViewPoint, RemoveDoublets, ReplaceOptionTaggedCell, SelectTaggedCell, ShowTo3DBoxedCell, ShowToTaggedCell, TaggedCellNotebook, TargetNotebook, TextDataCell, TextDataToTaggedCell

Please help me to test this package, and send feedback to ingolf.dahl@telia.com ! The package is intended for Mathematica 5.1 and 5.2, and has been developed on a Windows XP computer.

(The PrintToTagggedCell notebook, earlier available here, is now made obsolete.)

Download from http://web.telia.com/~u31815170/Mathematica/TaggedCells0p93.zip and unpack according to the readme file inside.

Version 0.93 (beta) published June 14, 2006.

   SetFaceAndFont, version 2.0.4

A palette to change face and font, but also to convert to input form, to add and remove brackets and parentheses, and to search the Mathematica online help, the Mathematica forums (e.g. MathGroup) and the entire web (possibly also including your own desktop). Comes with help files integrated with the Mathematica help.  The palette is intended for Mathematica 5.1 and 5.2, and has been developed on a Windows XP computer.

Download SetFaceAndFont204.zip and unpack according to the readme file inside.

Version 2.0.4 published September 14, 2005
Changes from version 2.0.3 to 2.0.4:
1. Peel changed to return executable cell from a SurfaceGraphics cell rendered as a RealTime3D cell. CopyAsInputFormK, "▪" and StyleRemove buttons corrected in behavior in relation to a SurfaceGraphics cell rendered as a RealTime3D cell. Most users do not use these features. If you are curious about such cells, see http://forums.wolfram.com/mathgroup/archive/2001/Apr/msg00346.html.
2. Some entries have been added to Help Master Index and some entries have been changed..
3. The language in the search result pages for Search, MG, Web buttons has been changed to English.
