Save a matrix to a temporary file

If a temporary file is preferred, the command
mtmp file;
may be used to save the current state. This file is held in a directory for temporary files specified by the environmental variable ``SILQCS_TMP'' (/tmp is the default directory), which is removed when a user exits from silqcs. The actual name of the temporary file looks ``silqcs-_~-'' + file. A user can use the saved temporary file by specifying its name just file instead of its actual path and filename.

The directory in which a temporary file is saved may be changed also by the command

settmpdir directory;
where directory is a path.
