There is one worksheet per chapter. They will be updated occasionally.

The DMat package contains an odd collection of procedures written over the years for very specific purposes. Almost all serve to illustrate concepts from theory.

The package is revised and updated occasionally.

Save the files maple.ind and maple.lib in an otherwise empty folder in any place you like. Keep the file names. Don't save the files with Maple's own files of the same names.

If the name chosen for the folder is libDMat and the folder is a subfolder in the folder Complex01141 on a drive with the name g, then do as follows at the beginning of the Maple session:

1. restart;
2. libname:="g:/Complex01141/libDMat",libname;
3. with(DMat);

Then the procedures in the package DMat should be available for use.

A worksheet, containing examples of the use of the proceedures in the DMat package is available. The accompanying text is in Danish, but most examples can probably be understood anyway.
