These instructions are for Windows 95 or 98. It is best to follow these instructions exactly. Little changes like renaming directories or placing them elsewhere that seem like they should work don't seem to work. Copy the vec_calc folder into the maple directory at the same level as the LIB directory is. Do not change the name of the vec_calc directory. You want the folder and its files. Open Maple and type in the command: libname; and hit enter. It will probably say something like: "C:\\Program Files\\Maple 6\\lib" which is its default library if you installed it on your C: drive. Make note of this library. If it shows any other libraries, make note of them because you will need to add them below. If you have installed Maple on a different disk than C: or in a different directory, change the entries accordingly in what follows. To cause Maple to automatically load vec_calc, you need to alter the command used to execute Maple. Right click on your Maple icon or shortcut, choose properties, and change the command line to make it look like shown below. You don't use the double \\ as shown above. "C:\Program Files\Maple 6\BIN.WNT\maple.exe" -b "c:\Program Files\Maple 6\lib" -b "c:\Program Files\Maple 6\vec_calc" This specifies the default library and the new vec_calc library. If your libname command above showed additional libraries, you need to include them on the command line too. After you have altered the command line, start up Maple and try the following: libname; (should show the libraries) with(vec_calc); (should generate some output) If you have gotten this far, you have succesfully installed the vec_calc package.
