13 \ingroup Matrix

15TVectorT
16
17Template class of Vectors in the linear algebra package.
18
19See the \ref Matrix page for the documentation of the linear algebra package
20
21Unless otherwise specified, vector indices always start with 0,
22spanning up to the specified limit-1.
23
24For (n) vectors where n <= kSizeMax (5 currently) storage space is
25available on the stack, thus avoiding expensive allocation/
26deallocation of heap space . However, this introduces of course
27kSizeMax overhead for each vector object . If this is an issue
28recompile with a new appropriate value (>=0) for kSizeMax
29
30Another way to assign and store vector data is through Use
31see for instance stressLinear.cxx file .
32
33Note that Constructors/assignments exists for all different matrix
34views
35
36For usage examples see `$ROOTSYS/test/stressLinear.cxx`
