It is easy to bum off of a friend who is running NC on the same system.
When your system administrator installed the code, he had several choices.
The first thing you should try is to start Mathematica by typing math and then type <<SetNCPath.m. If there are no error messages, then type <<NCAlgebra.m. Mathematica should respond with a sequence of statements indicating that various files are being loaded.
If Mathematica responds with Get::noopen: Cannot open SetNCPath.m, then additional steps are required as described below.
You need to determine where your system administrator installed NCAlgebra. The easiest way to do this is to ask your system administrator. If that is not easy and/or convenient, then you can type
Let us suppose that you know the location of the installation of NCAlgebra. Let us suppose that it is located in the directory /usr/local/NC.
Move into the directory where you want to use NCAlgebra (or create such a directory using the mkdir command). Create an init.m file with your favorite editor which contains the following lines:
AppendTo[$Path,"/usr/local/NC/"];
Get["SetNCPath.m"]; |
Type math and then type <<NCAlgebra.m. Then Mathematica responds with a sequence of statements indicating that files are being loaded.
Suppose that your friend has installed the code and he is willing to let you use his version of the code (see (6)), then you can follow this procedure:
$NCDir$ = "/home/JoeShmo/NC"

Now, follow the directions in Section 33.6.1.
