Naming Scheme

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.

GB | general band |

GE | general (i.e., unsymmetric, in some cases rectangular) |

GG | general matrices, generalized problem (i.e., a pair of general matrices) |

GT | general tridiagonal |

HB | (complex) Hermitian band |

HE | (complex) Hermitian |

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 |

SY | symmetric |

When we wish to refer to a class of routines that perform the same function on different types of matrices, we replace the two letters by ``yy''. Thus LA_yySV refers to all the simple driver routines for systems of linear equations that are listed in Table 2.2.

The last three letters
