class TVectorT<double>: public TObject


Template class of Vectors in the linear algebra package

Unless otherwise specified, vector indices always start with 0,
spanning up to the specified limit-1.

For (n) vectors where n <= kSizeMax (5 currently) storage space is
available on the stack, thus avoiding expensive allocation/
deallocation of heap space . However, this introduces of course
kSizeMax overhead for each vector object . If this is an issue
recompile with a new appropriate value (>=0) for kSizeMax

Another way to assign and store vector data is through Use
see for instance stressLinear.cxx file .

Note that Constructors/assignments exists for all different matrix

For usage examples see $ROOTSYS/test/stressLinear.cxx
