# LAPACK Compared with LINPACK and EISPACK

LAPACK has been designed to supersede LINPACK [38] and EISPACK [92,54], principally by restructuring the software to achieve much greater efficiency, where possible, on modern high-performance computers; also by adding extra functionality, by using some new or improved algorithms, and by integrating the two sets of algorithms into a unified package.

Appendix D lists the LAPACK counterparts of LINPACK and EISPACK routines. Not all the facilities of LINPACK and EISPACK are covered by Release 3.0 of LAPACK.
