Recursion leads to automatic variable blocking for dense linear-algebra algorithms

We describe some modifications of the LAPACK dense linear-algebra algorithms using recursion. Recursion leads to automatic variable blocking. LAPACK's level-2 versions transform into level-3 codes by using recursion. The new recursive codes are written in FORTRAN 77, which does not support recu...
