Other Handouts: Mixed Partials Handout, Lagrange Multipliers Handout,

Matlab demos: List of demos, Directory of demos to download <- It easier to download the whole directory since some m-files call other m-files in the directory.

Matlab Worksheets:

• The purpose of these worksheets is to introduce you to Matlab and in particular to show how Matlab can solve multivariable calculus problems which would not be reasonable to do by hand.  I want to emphasize that this is an introduction only.  We will only be scratching the surface of Matlab and in particular you should not expect to ``learn Matlab" in this course.  Instead you will learn some commands which will tell matlab to do certain things.
  
• Matlab tutorial (in postscript format) or here's another oneand yet another.
• Information about computer labs where you can work on the matlab homework assignments is available here. Also see the comments here for more information about how to get the software to work, although this link is oriented to making M-books which you won't be doing. MATLAB tutoring is available in two of these labs at hours posted here. (If you would prefer to work on your own computer, you might wish to purchase your own copy of The MATLAB Student Version, available at the University Book Center for about $100 or from The MathWorks web site. 
• Here are more extensive matlab materials for Math 241.  These are from the Spring 2002 Math 241 which used matlab more extensively than we will.
  
• There will be Matlab tuoring available in the computer lab in the PG2 parking garage. The times are Monday 9-4, Tuesday 10:20-3:20, Wednesday 9-4, Thursday 11-3,  Friday 10-4.  Note: due to renovations in PG2 the tutoring will be in room 0203 of the math building at the beginning of the semester, after which it will move to PG2.

• Here is your first Matlab assignment, due MONDAY, October 14.  Here is a matlab session doing the examples in the assignment which you may want to cut and paste from.  It also has some additional material.  Here is another version which works on older versions of matlab.  

• Here is your second Matlab assignment due FRIDAY, November 1.  Here is a matlab session doing the examples in the assignment which you may want to cut and paste from.  It also has some additional material.  Note that since this assignment has no graphics, you can easily run matlab from your own computer by telnetting to wam.  I give an example in the matlab session linked above. Some versions of matlab seem to give you trouble if you use the subs command with an empty list.  So if you get lots of errors when gnerating your table T, and one of your lists of points is empty, you could eliminate it from your table.  For example, if there were no critical points of f you could eliminate the bx by ...   line.  Here is a matlab session with lots of errors and their corrections.

• Here is your third Matlab assignment due Friday,  Nov 22.  Here is a matlab session doing the examples in the assignment which you may want to cut and paste from. To do these problems you will need to download two files, nquad.m and ezint241.m.  Problem 2 involves finding the area of a parameterized surface.  Refer to old class notes and the section 14.9 handout for the needed formula.  Also an example of this is in the link above.

• Here is your last Matlab assignment due Wednesday, December 11.  Here is a matlab session doing the examples in the assignment.
