Naming Conventions

Argument types. Types of all arguments of Fortran routines in this Quick Reference follow these conventions:

IMPLICIT COMPLEX (C)
IMPLICIT DOUBLE PRECISION (D)
IMPLICIT INTEGER (I-N)
IMPLICIT DOUBLE COMPLEX (Z)
CHARACTER*1 compq, compz, diag, eigsrc, howmny, initv, job, norm, order, range, side, trans, transa, transb, uplo, vect
LOGICAL select

Arrays. Names of Fortran arrays are typeset in UPPERCASE letters, and names of all other Fortran arguments are in lowercase letters.

Names of routines. The first letter of a routine name identifies the type of the result:
s    COMPLEX
d    DOUBLE PRECISION
c    COMPLEX
z    DOUBLE COMPLEX
i    INTEGER

To specify the group of routine names that differ in the first letter, this Quick Reference uses the question mark (?). For example, ?getrf refers to the routines sgetrf, dgetrf, cgetrf, and zgetrf.
