[Toon-members] TooN SymEigen.h internal/config.hh

[Damian Eads]

CVSROOT:        /sources/toon
Module name:    TooN
Changes by:     Damian Eads <eads>      09/08/26 07:49:20

Modified files:
        .              : SymEigen.h 
        internal       : config.hh 

Log message:
        Added constructor to SymEigen(int) for dynamically sized matrices 
without immediately decomposing after initialization. This is analogous to 
SymEigen() for statically sized matrices. Put Internal:: in front of 
symeigen_condition_no to fix symbol not found error.
