How can I obtain a LaVectorDouble object which is a submatrixview of a LaGenMatDouble?

We are using Lapack++ for our matrix calculations. One of the features is the use of submatrixviews; objects that refer to the same spot in memory. Example: LaGenMatDouble W = LaGenMatDouble::rand(3,4); LaGenMatDouble A = W(LaIndex(0,2), LaIndex(1,3)); LaGenMatDouble b = W(LaIndex(0,2), LaIndex(0,0)); A and b are now submatrice...
