Template class of Vectors in the linear algebra package.

See The ROOT Matrix Linear Algebra classes. for the documentation of 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
