Dear Class,

The maple2018 instructions apply to maple 9.5, 11, 12, 13, 14, 15,
16, 17, 18, 2015, 2016, 2017 with changes to command lines, e.g., change "maple2018"
to "mapleV18" or "mapleV12". Some of the older maple versions don't
work due to license agreements, e.g., mapleV18.

To use maple 2018 on the local unix systems, invoke it by command
line

 xmaple &
  or
 xmaple2018 &

To use maple 9.5 with the classic window interface [no java],
invoke it by the command line

 xmapleV9.5 -cw &

After starting maple with GUI interface, 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 2018, 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 works in maple 2018. 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): # Deprecated, still in maple 2018.
           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 2018 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 maple2018 installation in Program Files. There is
no classical interface available in linux V12 through 2018: use V9.5.

The bare-bones terminal interface maple 2018 is launched on a unix
system as follows:
