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
(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 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.
