The eig() command provides easy access to the functionality of the 
LAPACK DSYEV routine.  However, there are times when it is useful to 
use options available only through the DSYEVX expert driver. For
example, if I'm interested only in those eigenvalues of a matrix 
in a particular interval, DSYEVX can find them.  
 
I had hoped that eig() would have options to get at this functionality,
but it appears that it doesn't.  Is there some relatively easy way to 
do this in MATLAB? I realize that this could be done with a mex file, 
but that seems like a lot of work...
