Matlab on Athena has been updated as of 1/30/91, but the previous version is still available. To run the older version of Matlab, type: add matlab.old matlab (This version of Matlab is not available for the DECstation.) You should have no reason to use the old version of Matlab, and Athena strongly advises moving to the new version, since the old version will eventually be discontinued. If you find major incompatabilities in the new matlab and must use the old matlab, please reports these Athena through OLC or the Faculty Liason. For more information about Matlab, type "help" while inside the program.
