Dear Class,

The maple 2018 instructions apply to maple 2015, 2016, 2017, V9, V9.5,
V10, V11, V12, V13 with obvious changes to command lines, e.g.,
change "maple2018" to "maple2015" or "mapleV11".

In late 2018, there is no maple V14, V5, V16, V18. These
versions have been removed.

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

 xmaple2018 &

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

 xmapleV9.5 -cw &

After starting xmaple2018 or xmapleV15, 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 xmaple2018, 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 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 maple 2018 installation in Program Files.

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