Announcements

  • Regarding Exercise 2.4.4 on Assignment 2, try generating the matrix A (first two lines of provided code in 2.4.4) by the commands

    r = zeros(1,n); % zero vector with n entries
    r(1:2) = [2, -1];
    T = toeplitz(r); % Toeplitz matrix
    E = speye(n); % nxn identity matrix, stored sparsely
    A = kron(T,E) + kron(E,T); % Kronecker sum
    % A is the discrete Laplacian in the standard ordering
    p = symamd(A); % permutation for the symamd ordering
    A = A(p,p); % discrete Laplacian in symamd ordering

    This should work in octave and matlab. It avoids using delsq and numgrid which only work in matlab.

  • We will use Matlab (available in the math department computer labs) or GNU Octave (a free alternative to Matlab) for linear algebraic and other computations. There are many freely available resourses to familiarize yourselves with this software. Here are some options to get you started:
    Matlab Primer, Matlab Guide (by Xenofontos), Octave Tutorial (by Long), and these Matlab/Octave basics.

  • Safety on Campus: The University has developed resources and a Campus Safety Plan for students, faculty and visitors. Also become familiar with the WSU ALERT site.
