[CHM 330] Interesting Bug

If while you are using my program to search for eigenvalues you get a 
"double" as in the following picture.

Don't worry.  This is due to the small stepsize I used when searching 
for eigenvalues to graph them.  The good news is that, using this 
example, you know you have an odd parity eigenvalue on the domain 
[0.75,0.80].   If you use those values and the other part of the program 
to actually locate the eigenvalue it will return the correct alpha value.
