---|---|---|---|---|

SO31.plt | (1 2) | 1.2 | wmfarr | Code to manipulate four-dimensional Lorentz transformations (i.e. SO(3,1) group elements). |

amb.plt | (1 0) | 1.0 | wmfarr | The classic ambiguous operator. |

array-ec.plt | (1 0) | 1.0 | wmfarr | SRFI-42 eager comprehensions and generators for SRFI-25 arrays. |

bh-tree.plt | (1 0) | 1.0 | wmfarr | Create and manipulate Barnes-Hut octtrees.These trees are useful in N-Body simulations as an efficient datastructure for computing forces and potentials. |

deriv.plt | (3 0) | — | wmfarr | MzScheme language which extends numerical operations to allow for automatic differentiation. |

mzgsl.plt | (3 0) | — | wmfarr | Bindings to the GNU Scientific Library for MzScheme. See the Science collection for native MzScheme libraries which implement much of this functionality. |

nbody-ics.plt | (1 0) | 1.0 | wmfarr | Initial conditions for N-body simulations.Currently provides cold and hot (any ratio of KE/PE) constant-density spherical distributions and plummer models. |

pairing-heap.plt | (1 0) | 1.0 | wmfarr | The pairing-heaps.plt package provides a unit for creating and manipulating pairing heaps. To learn more about pairing heaps, see the Wikipedia entry on pairing-heaps. The heaps created by this package are "persistent", meaning that operations like "insert" create a |

permutations.plt | (1 3) | — | wmfarr | Generate and manipulate permutations. |

plt-linalg.plt | (1 13) | — | wmfarr | Simple linear algebra operations in double-precision for PLT Scheme.Uses LAPACK and BLAS for operations |

simple-matrix.plt | (1 1) | — | wmfarr | Very simple and basic matrix/vector operations and datastructures |

srfi-4-comprehensions.plt | (1 1) | 1.0 | wmfarr | SRFI-42 comprehensions and generators for SRFI-4 vectors |
