Unclaimed problem sets 8 and 9 papers

These may be retrieved from Prof. Eisenberg during the first two weeks of the Spring, 2002, semester. Final exam papers may also be inspected then.

Making bitmap for virtual raster array image—see Notes page

Always use raster4x.ijs rather than raster4.ijs

Using lapack—see the Notes page on this site

How to print graphics from J (09/27/01)—see the Notes page

Fix to script cobweb.ijs available (09/26/01)

To simplify use of cobweb.ijs, I’ve edited it to include the sentence:

require ’plot numeric’

The edited version is available on the Files pages.

Bug-fixes for J 4.06 available

These won’t be applied to the UMASTR installations for a while, but if you have installed J on your own computer, you may want to apply these fixes.

Download these from the Files page. For each, unzip to the main J directory and be sure your unzipper is set to preserve paths (e.g., in WinZip, “use folder names”.

The files LocalJ.zip and InstallJ.pdf have been updated to include these fixes.
