This index lists related pairs of real and complex routines together,
for example, SBDSQR and CBDSQR.
Driver routines are listed in bold type, for example SGBSV and
CGBSV.
Routines are listed in alphanumeric order
of the real (single precision) routine name (which always begins with S-).
(See subsection 2.1.3 for details of the LAPACK naming scheme.)
Double precision routines are not listed here;
they have names beginning with D- instead of
S-, or Z- instead of C-.
This index gives only a brief description of the purpose of each
routine. For a precise description, consult the specifications
in Part 2, where the routines appear in the same
order as here.
The text of the descriptions applies to both real and complex routines,
except where alternative words or phrases are indicated, for example
``symmetric/Hermitian'', ``orthogonal/unitary''
or ``quasi-triangular/triangular''. For the real routines is equivalent
to .
(The same convention is used in Part 2.)
In a few cases, three routines are listed together, one for
real symmetric, one for complex symmetric, and one for complex Hermitian
matrices (for example SSPCON, CSPCON and CHPCON).
A few routines for real matrices have no complex equivalent (for example
SSTEBZ).
