Yes, it is just about vectors and matrices where each element has
different dimensions. It is useful for certain calculations. Leland
Brown gave an example from his own program:

My apologies for lack of imagination to get a good name. I picked
'linear algebra' just becasue I was sure that 'geometry' (suggested by
Andy) is certainly a bad name. But now Geoffrey Irving has now a better
idea to call it 'vectors'. Maybe even 'small vectors'.

If you want to suggest another name, please go on :)
