- 1.
- The specifications that follow give the calling sequence, purpose,
and descriptions of the arguments of each LAPACK driver and
computational routine (but not of auxiliary routines).
- 2.
- Specifications of pairs of real and complex routines have been merged
(for example SBDSQR/CBDSQR).
In a few cases, specifications of three routines have been merged, one for
real symmetric, one for complex symmetric, and one for complex Hermitian
matrices (for example SSYTRF/CSYTRF/CHETRF).
A few routines for real matrices have no complex equivalent (for example
SSTEBZ).
- 3.
- Specifications are given only for single precision routines.
To adapt them for the double precision version of the software, simply
interpret REAL as DOUBLE PRECISION, COMPLEX as COMPLEX*16 (or DOUBLE COMPLEX),
and the initial letters S- and C- of LAPACK routine names as D- and Z-.
- 4.
- Specifications are arranged in alphabetical order of the real routine
name.
- 5.
- The text of the specifications has been derived from the leading comments
in the source-text of the routines. It makes only a limited use of
mathematical typesetting facilities. To eliminate redundancy, AH
has been used throughout the specifications. Thus, the reader should
note that AH is equivalent to AT in the real case.
- 6.
- If there is a discrepancy between the specifications listed in
this section and the actual source code, the source code should be
regarded as the most up-to-date.
