Assignments for MA443 (as of 14dec)
scores so far as of 14dec
Scientific work is very much based on cooperation, on making use of other
people's work. However, if one presents work under one's own name, one
is honor-bound to list any such sources used. Failure to do so is called
cheating and results in loss of one's scientific standing (and worse).
This also applies to homework handed in under one's own name. Specifically,
the instructor has nothing against students discussing homework
assignments provided such cooperation is explicitly acknowledged in the
homework handed in. Of course,
each student separately hands in homework and, by putting his or her name
onto the homework, certifies that
this is their own work. If they have discussed some or all of the
problems with others and this has influenced what they
finally produced, such influence should be explicitly acknowledged. Merely
copying someone else's homework is unacceptable, even if the copy explicitly
states that this was copied from so-and-so's homework.
The instructor will be alert to possible cheating; in case of cheating (on
homework or exams), the instructor intends to impose penalties whose
negative effect is much larger than the potential positive gain from

policies and comments
If a problem asks you to construct a MATLAB m-file and/or to carry out some
MATLAB calculation, be sure to hand in the clean and
well-commented m-file(s) and/or script that carries out the calculations,
along with a diary (edited to be short and to the point) and/or plot(s)
showing the relevant answer(s) generated by your script.
Mark all homework clearly with your name. In addition, put the first letter of
your last name boldly into the upper left corner of the first page of your
homework, to make it easier for us to sort it and for you to find it again when
it is handed back.
The present plan is to give
an assignment every week, due at beginning of class on Monday of the next
week, to include (perhaps) some T/F questions in addition to several
problems some of which might ask you to prove something.
policy on late homework
- Any homework not handed in by the BEGINNING of the class period of the
due date loses 10%.
- Any homework not handed in by 5p of the due date loses 25%.
Any homework not handed in by noon of the day after the due date loses 100%.
- To `hand in' homework outside class, put it into the instructor's mailbox
(fifth floor of CS & Stat) or hand it directly to the instructor (if you can
find him :-).
policy on grading disputes
Any discussion concerning the grading of a particular homework
must be initiated within one week of the day when that
homework was returned in class.
