Dear Math 293; 12/4/96
LECTUE ERROR
^^^^^^^^^^^^
On about Wednesday October 16, 1996 both Professors Ruina and Terrell
showed incorrect MATLAB commands for using eigenvalues and eigenvectors
to solve systems of linear, constant coefficient, homogenious, ODEs.
The mistake was repeated by most students in their solutions to HW8
and by the TA when he wrote up the 'official' solution (and called
it soln to HW7). (Students lost no credit if they duplicated the
mistake in their solution to Prelim 2.)
A correct set of MATLAB commands, and an explanation of the mistake,
is in the course WWW page under MATLAB samples in a file
called eig_ODE_soln.m. Click away, read all about it,
and correct your notes.
All blame goes to me. Sorry.
