Mathematica Laboratory
| Availability |
Mathematica is installed on many Computers in the basement of the Science center.
It might also be installed on the computers in the houses. If you want to try
installation of mathematica on any of the Harvard computers,
start here.
|
| Getting the notebook |
Get it here , save it on your disc and
import it to mathematica.
|
| Running mathematica |
Mathematica is started like any other application on Macintoshs or PC's.
On Unix, just type "mathematica" to start the notebook version, or
"math" to start the terminal version.

Mathematica)

| Printing |
See the
Printing guide of HASCS. Note that you need to have a
printing budget . |
| Printing problems |
- I tried to print my notebook but there is no printout.
- You might have no printing budget. The printer would spit out a page telling this.
- You might have written the notebook to a PS file on your computer instead of sending it
to the printer (you can chose so at the printing dialog box).
- I want to save paper. How do I print out only a part of the notebook.
- Chose "print selection" instead of "print" in the Mathematica notebook. The selected cells will be printed.
- Alternatively, open a new notebook, cut and paste the part you need to turn in into
the new notebook and print that out.
