The name of each LAPACK95 routine has been made as similar as possible to
its name in LAPACK.
All driver and computational routines have names of the form LA_YYZZZ, where for some routines the 8 character is blank.
The two letters YY indicate the type of matrix (or of the most significant matrix). Most of these two-letter codes apply to both real and complex matrices; a few apply specifically to one or the other, as indicated in Table 2.1.
|GE||general (i.e., unsymmetric, in some cases rectangular)|
|GG||general matrices, generalized problem (i.e., a pair of general matrices)|
|HB||(complex) Hermitian band|
|HP||(complex) Hermitian, packed storage|
|PB||symmetric or Hermitian positive definite band|
|PO||symmetric or Hermitian positive definite|
|PP||symmetric or Hermitian positive definite, packed storage|
|PT||symmetric or Hermitian positive definite tridiagonal|
|SB||(real) symmetric band|
|SP||symmetric, packed storage|
|ST||(real) symmetric tridiagonal|
