Project 2: code near bottom pg 15: either all of these should be "L",
           or the last line should be "L = kron(L1,I) + kron(I,L1);"

Project 1: ellipse.m referred to major/minor axis when it should have said
           major/minor semi-axis.  Hopefully the plots made this clear enough.
           New version uploaded.

Project 3: Exercise 1: should say "steady state" (not "stage").

rev 3

Project 2: bottom of pg15 "L1 = lap1d_matrix(x,dx);" is incorrect, it
should have an N instead of x: "L1 = lap1d_matrix(N,dx);"

rev 2

Project 3: remove some potential ambiguity from the twin primes bit
and from the definition of "nextprime"

rev 1

Project 3: Make Exercise 6 a little more open-ended: find the best
estimate of Brun's constant that you can with at most the first 10000
twin prime pairs.

pg 6: tanh(s^2*y) was missing multiplication.

rev 1

pg 10: changing vertical axis, this is incorrect.
       Instead use ylim([-1.2 1.2]) after making the plot.
