Hi Daniel,
The intent of the Vector and Matrix class templates is to be used for
linear algebra operations such as matrix/vector products. These
operations have a different action
than the elementwise array/array products performed by the Array class
template.
In addition, one could add specialized functions to these Vector and
Matrix classes,
such as computing the trace of a Matrix.
As you have noted, the Vector and Matrix classes are not well documented
and are
incomplete. I have been working recently on trying to get the Vector
and Matrix
classes to share the same expression template system as the Array class,
in order to
reduce the amount of code in blitz. Once this is done, perhaps we can
try to flesh out
these classes some more and add documentation. Linear algebra was never
really the
main focus of blitz, so this is kind of a low-priority area of work.
Regards, Julian C.
