Previous announcements
- Monday, April 25 We will have class on April 29th and May 2nd of reading period, possibly also on May 4th if we do not finish covering the material by May 2nd. The later class periods (9–10am on May 6th, 9th and 11th) will be converted to office hours in B&H 158 (across the hallway from our usual classroom). There are two more homework assignments: hw10 due on May 7th, and hw11 due on May 14th.
- Saturday, March 19 Please note the following when doing HW5: In Problem 2, for the first part (generating A21–A23) assume boundary condition (i) with gamma = 2; that is, take the slope at the left boundary to be 2. For both parts, when deriving the equations for the b's, try to make the coefficients whole numbers before writing the system in matrix-vector form. In Problem 3, the profile of the dog starts at x = 1 while the question asks you to evaluate Curve 1 at the points linspace(0,17,70)—that's a typo: you're supposed evaluate the curve at linspace(1,17,70).
- Monday, March 14 From this week on, only a limited number of m-files will be available from the webpage. This is because I am concerned that some people are simply downloading the files and using them for homework, with little to no understanding or thought as to what goes into developing the code. To learn to write Matlab code, one has to actually write Matlab code. Those who come to class and type in the code at their laptop computer or write it down by hand will get a hard copy of the code for reference, but this code will no longer be posted on the webpage—the point is that each piece of code we write in class you should, at least once, type out by yourself. If you must miss class for whatever reason, ask a friend to take notes and pick up a handout for you, or see me during office hours.
- Thursday, March 10
For HW4, the data files are in the Scorelator system with .txt (rather than .dat) as their extension. So if you are using the "load" command in your homework script to read in the data, you need to change the statements to
"load temp.txt", "load decay.txt" and "load yeast.txt" (otherwise Scorelator won't find the files and will return an error). When submitting your homework, you do not need to upload any of the data files yourself; upload only your m-file(s).
Also note that for Problem 2 part (a), you are meant to use the ln(y) transformation, not fminsearch; but fminsearch should be used for part (b).
- Friday, Feb 25 The deadline for hw2 has been extended by one day to Mar 3 (Thu) 4:00am EST. In Problem 2, retain at least 6 decimal places in those entries of the matrix M that you obtain by calculation, otherwise the rounding errors will compound as the matrix is iterated.
- Friday, Feb 11 The deadline for hw0 has been extended by two days to Feb 14 (Mon) 4:00am EST and the number of attempts allowed has been increased by 3 (to 8 in total).
- Wednesday, Jan 26 Please see above for information about the computer TA, who is available to help with any Matlab-related questions.
