LLANO: Lazy evaluation, operator templates, and numerical linear algebra

Abstract
A new C++ matrix algebra package, LLANO, is presented.
Operator templates for overloaded operators are
used to produce highly efficient yet elegant code.
The templates have the effect of deferring operations until
assignment. However, care is taken in the interaction of addition with
matrix products to avoid escalating operation counts and enable the use
of optimized library routines.
Numerical examples indicate excellent performance, both for nontrivial
algebraic expressions and for a matrix factorization implemented
through LLANO.
