Please read carefully the following information before downloading

There is no "time bomb" in the demo version. The only limitation is speed. What you download is a lightweight client application. It has the same interface and functionality as the standard version. The mathematical engine however is located on our server and the client application has to talk to it over the Internet. This configuration provides you with unlimited access to all the features of the product whose performance will depend on the speed of your Internet connection and the number of users connected to the server. The trial version runs at least 300 times slower than the standard version. The average computation time of a simple expression is normally 0.01 - 0.03 seconds. The demo version may sometimes spend over 3 seconds on the same operation. You may also experience connection timeouts. However, you will get a complete idea of the functionality.

The expressions that you enter are compiled every time you make a change. Compilation takes place on the server. For instance, if you enter a simple expression like sin(x), it contains an unknown identifier x. You should expect this identifier to appear in your parameter list. Then you will be able to assign a value to x. There is no sense in doing anything else (like pressing "Start") BEFORE the name of the unknown identifier appears in the list. If your Internet connection is slow, this may take several seconds. Please have patience. A good way of avoiding disappointing error messages on a slow connection is to take a little pause before hitting "Start" after having changed  the expression.

If you are using any mode different from the Calculator mode, be sure to mark one of your parameters variable (or leave one value field blank) otherwise your expression is considered constant (in particular your graph will be flat). To mark a parameter variable, either click on the field containing the "=" sign or press Alt-v when the focus is in the value field of this parameter.
 

Installation instructions

You are resposible yourself for installing the Java runtime environment on your computer before installing Math•Mate Java Edition. Then follow the instructions below:

1. Download the file mathmate.zip.
2. Unzip it to a directory of your choice.

How to run the program

Use one of the scripts provided for the Windows, OS/2 and UNIX operating systems to launch the program. If you are using JDK, use files named mathmate.bat, mathmate.cmd, mathmate.sh respectively. If you are using JRE, use files named mmjre.bat, mmjre.cmd, mmjre.sh respectively. All you need to do is to switch to the directory to which you unzipped the files in the previous step and type the name of the script.
 
 

Windows instructions

1. Connect to the Internet
2. Open a DOS window
3. Type
   c:
   cd \mathmate
   mathmate.bat

UNIX instructions

1. Connect to the Internet
2. Open an xterm window
3. Type

cd ^~home/mathmate
mathmate.sh

This will launch the graphical client application. To run the text-mode client, use the -n command line switch:
mathmate.cmd -n .

Alternatively, you can set the environment variable CLASSPATH to include mathmate.jar.
For example, in the Windows environment, your CLASSPATH may look as follows
CLASSPATH=.;c:\jdk1.1.4\lib\classes.zip;c:\mathmate\mathmate.jar

Then launch the program using
java mmtrial [-n]
Alternatively, with JRE use the command
jre -cp mathmate.jar mmtrial [-n]

How to get help

Complete help for Math•Mate Java Edition is provided in the HTML format. The help files reside in the help subdirectory of the Math•Mate's directory. They can be viewed with your favorite browser. The top-level file is mmhelp.html. Alternatively, browse the help online.

Help may also be used inside Math•Mate Java Edition. Since Java has no help engine so far, Math•Mate needs to know how to launch your browser. Use menu Settings/Browser path  to set the complete path to your browser. It will be recorded in a file browser which you will be able to locate in the Math•Mate's directory (and even edit manually if necessary). This file's contents will be used next time to launch your browser.

Caution: the above mentioned feature is provided for your convenience, but it is potentially insecure in the sense that whatever you put into this file will be executed when you choose the Help/Help menu. The risk is exactly the same as if you typed a wrong command at a command prompt. In any case, the mistake will be yours and we can't assume responsibility for any damage caused to your files or computer.

If you have trouble installing or running Math•Mate please read the Frequently Asked Questions information.

To help you get started quickly, here are three sample Math•Mate operations to start with.

Task: Calculate sin(x) for x = 1.5

Task: Integrate sin(x)*y with respect to x from 0 to p where y=2

Task: Plot sin(e^x) on [0, 2p]
