Dear Class,

The same instructions apply to maple 9.5, 11, 12 and 13,14,15.

To use maple 12 on the local unix systems, invoke it by command line

 xmapleV12 &
  or
 xmapleV12.01 &

To use maple 12 with the classic window interface [no java], invoke it
by the command line

 xmapleV12 -cw &
  or
 xmapleV12.02 -cw &

After starting maple 12, set the OPTIONS on the tool menu as follows:

     Display --> Input display --> Maple Notation
         Display --> Output display --> 2D-Math Notation
         Interface --> Default format for new worksheets --> Worksheet
         Apply Globally

When working with maple 12, you should see red text on input and blue
text on output. If your typing is black, then exit Maple, start it
again, and look for a change. If no change, then repeat the steps above,
assuming a typo.

The linalg package is supposed to work in maple 12. Loading of package
LinearAlgebra and then loading package linalg should make the commands
of both available.

Example 1: A:=<<1,0> | <2,3>>; # Enter cols of matrix A
           b:=<-1,1>;
           A.b;    # multiply matrix A against column vector b.
           det(A); # No answer, needs linalg package
           Determinant(A); # No answer, needs LinearAlgebra package
           linalg[det](A); # works
           LinearAlgebra[Determinant](a); # also works

Example 2: with(linalg):            # Depreciated, still in maple 15.
           C:=matrix([[1,2],[0,3]]);# In textbooks. Enter C by rows.
           eigenvects(C);
           Eigenvectors(C); # No answer, error message

Example 3: with(LinearAlgebra):
           F:=Matrix([[1,2],[0,3]]);# Enter F by rows.
           Eigenvectors(F);

Example 4: with(LinearAlgebra):with(linalg):
           A:=<<1,0> | <2,3>>;      # Enter A by cols.
           Eigenvectors(A);Determinant(A);
           eigenvects(A);det(A);

To set up maple 12 on linux, windows and Mac OS/X systems, follow the
advice above. To run the classic window interface under 32-bit windows,
launch the application "cwmaple" located in the win.bin subdirectory of
the maple12 installation in Program Files.

The bare-bones terminal interface maple 12 is launched on a unix
system as follows:
