TVectorT< Element > Class Template Reference

template<class Element>
class TVectorT< Element >

TVectorT.

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 views

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