This section describes briefly the functionality that does not warrant
a large explanation. Further implementations include a means for
loading new data or saving it as a different filename. There is also
a menu option for clearing a set of files. This option was
included to remove all property files
. This is useful since
a great deal of operations may be performed on a file, such that if
that data is altered, then these files become invalid. Rather than
update all the property files, it seemed an easier solution to request
the user to remove them.
A font option allows the data to be altered in size. Together with the scale option and the option for changing zeroes or non-zeroes to pixels, this forms a useful tool for viewing large matrices.
Tcl provides a simple way of creating postscript formats of data. Both the textual and the graphical views of the algebraic data may be sent to a postscript file, or printed to the printer specified in the configuration file.
There is also a simple help file which describes the user functionality in more depth.
