- Installing Graphmatica:
- -----------------------
- To be able to use the on-line help facility, you should place the six
- .HLP files on the same disk and directory as the executable file. Then,
- before you run Graphmatica, change the current drive/directory to where
- those files are. For example, to install Graphmatica from the disk in
- drive A: to some directory C:\GRAPHICS, you would type:
- C:\>copy a:graphmat.* c:\graphics
- C:\>copy a:grmat?.* c:\graphics
- C:\>copy a:*.gr c:\graphics
- and to run the program, you would type:
- C:\>cd c:\graphics
- C:\GRAPHICS>graphmat
-
-
- Notes:
- ------
- Please do not edit any of the files GRMAT*.HLP. They are formatted
- especially for use under the Graphmatica help view function, broken up
- into screens of 23 lines. Altering these files may result in abnormal
- page breaks and prevent effective use of the online help.
-
- What's new in version 3.50b:
- ----------------------------
- Added new checking to prevent floating point errors drawing ODEs
- that go off screen very steeply.
-
- What's new in version 3.50a:
- ----------------------------
-
- The following bugs in version 3.50 were fixed:
- 1. tanh function incorrectly produced "10^x"
- 2. Functions which are not always positive could cause fatal floating point
- errors when graphed with logarithmic graph paper.
-
- In addition, I have added routines to trap floating point errors in all
- calculations for graphs and drawing graph paper. This should virtually
- eliminate the possiblity of crashes due to really complex equations or
- really huge or small grid ranges.
-
- For a complete list of what's new in version 3.5, see Appendix C of
- GRAPHMAT.DOC.

-
- How to get the latest version:
- ------------------------------
- The latest version of Graphmatica for DOS and Windows will always be
- available on CompuServe and on FTP sites on the Internet.
-
- On CompuServe, GO SCIENCE to enter the math & science forum and look in
- library 5 (mathematics) for GRMxxD.ZIP (DOS) or GRMxxW.ZIP (Windows),
- where xx will be the latest version number.
-
- On the internet, use FTP or gopher to access archives.math.utk.edu
- and look in the software/msdos/graphing/grmat directory for the latest
- versions. The Windows version is also available at the CICA archives
- (ftp.cica.indiana.edu) in the win3/util directory. Both of these sites
- are mirrored at a number of places, including wuarchive.wustl.edu.
-
- How to contact me:
- ------------------
- You can always send me e-mail at 70711,2071 on CompuServe. On the
- internet, send mail to khertz@pacbell.net or see my WWW page at
- http://server.berkeley.edu/~khertz/ksoft/ksoft.html
-
- I do NOT provide telephone support. Please don't try to get my number
- through directory assistance, as you will probably just bother my
- parents.
-
- Worst comes to worst, you can write me a letter and mail it to the
