Lists of LFRT function ordered by topics
| The following functions of
the directory @lfr are implicitly called:
ctranspose, horzcat, minus,
mrdivide, mtimes, mpower, plus,
uminus, vertcat. These functions permit the user
to manipulate lfr-objects like matrices. Other functions of
@lfr that can be explicitly called: |
