Supermongo may loose a lot of its ease of use if you can't recollect and
edit commands from the history to be run again. This may be the case
because sm doesn't correctly work with the particular terminal software it
is run in.

However, there is an easy way of fixing this: Supermongo's termtype
command. You can use this to change the way Supermongo communicates with
your terminal to a language that your terminal unterstands. The file
/etc/termcap contains the available options. For me, it worked to say

: termtype ansi77

in order to get sm history to work like it should.

You might have wondered why the authors of supermongo have only implemented matrix routines for quadratic matrices in their standard macros (see help matrix in supermongo for details). So have I. In case this helps you, feel free to use the following generalizations of some matrix macros to n x m - matrices. I only implemented those I needed and did some testing on them, this is not a complete set of what you might require. The macros are named like the usual ones, but with a suffix "2".
