Fall 2007 Math 253 Matlab Assignment 5

Description

1. Students will work together in their assigned teams. In this manner they will:
   
   
   • finish assignments more quickly and cross-check each other's work;
     
     
   • give their TA a more manageable amount to grade;
     
     
   • build their networking and cooperation skills.
     
     
2. In Chapter 9 of your Matlab lab manual (A Matlab Companion for Multivariable Calculus; designation: C for Cooper, your lab manual author), on pages 192-194, do the following exercises.
   
   
   • c192x01, c192x02, c194x04, c194x05, c194x06
   
   
3. For each problem, you'll work out of the MATLAB Editor. You'll interactively save and run your MATLAB M-file, writing input and output to a diary file. If you have graphics, save your figure files and export them as Encapsulated PostScript. For example, the four files for the first problem are:
   
   
   • c192x01.m: M-file with MATLAB input commands and comments
   • c192x01.txt: diary file with input and output interspersed
   • c192x01.fig: figure file containing graphics
   • c192x01.eps: Encapsulated PostScript printer file
   
   
4. You'll print out the .txt and .eps files via xprint. Do any hand work on ruled notebook paper or engineering green graph paper.
   
   
5. Regarding the figures themselves, interactively edit them. Put on labels; insert text or arrows; change line thicknesses; etc.
   
   
6. This assignment is due on Thu, 18/Oct, at the START of computer lab. Be sure to manage your time according to your schedule. Do NOT put things off!
   
   
7. When you finish, you will turn in the documentation of your Matlab work to your TA. Everyone will do this on Thu, 18/Oct (not before), to make things easier for your TA. In this regard, make sure the following information is on a cover sheet.
   
   
   • Fall 2007 Math 253 Matlab Assignment 5
     
     
   • Section 50x, Your Name, Student ID [here x = 4-6]
     
     
8. Various MATLAB videos that you have viewed in advance show how to use xprint to print your diary .txt and graphics .eps files from CalcLab. Alternatively, transfer your MATLAB files to your TAMU open access lab H: home drive via WinSCP, load them into the Windows version of MATLAB, and print locally.

Notes

• There are samples of the types of exercises you have to do in Chapter 9 of your lab manual.
  
  
• Also look at the MATLAB examples in our class lecture handouts for additional information, especially regarding riemann, int, and smi.
  
  
• You may also find my ss routine ("simple Simpson") useful. It is more general and quicker to use than Cooper's simp2 and simp3 routines.
  
  
• On c192x02b, the MATLAB Symbolic Math Toolbox returns an exact answer (call it V) in terms of Fresnel sine and cosine integrals. To obtain a floating point approximation to V, put this MATLAB command after your integration, as stated in Cooper. (Thanks to Jason Knight for pointing this out. Your wayward instructor hadn't read the problem!)
  • V_float = double(V)
  
  
• You may wish to print out intermediate versions of your Matlab code or figures to discuss with your instructor, TA, or MATLAB help session staff.
