# Maple Packages

Bare-bones Maple is quite powerful, but Maple provides a number of packages that dramatically enhance its usefulness. These include packages to enlarge plotting capabilities, do linear algebra, generate random numbers, and other useful things. A list of just a few such packages follows.

Package | Purpose | Example Procedures |
---|---|---|

DEtools | Differential Equations | DEplot, autonomous, varparam, poincare |

Exceltools | Facilitate access to MS Excel | Export, Import |

GraphTheory | Create, test and draw graphs | DrawGraph, Graph, Digraph |

LinearAlgebra | Calculations with matrices and vectors | Transpose, Determinant, Dimension, Eigenvalues |

MathML | Translate to and from MathML | Export, Import |

numtheory | Number Theory | cfrac, kronecker, fermat, rootsunity |

orthopoly | Orthogonal Polynomials | G, H, L, P, T |

plots | Fancy Plots | contourplot3d, implicitplot, display, loglogplot, polygonplot |

RandomTools | Random number generation | Generate, MersenneTwister, GetState |

RootFinding | Find roots numerically | Analytic, EnclosingBox, NextZero |

XMLTools | Manipulate XML files | AddAttribute, HasAttribute, IsAttribute, CleanXML |

There are a couple of ways to use packages. The easiest is simply to
load the entire package into Maple using the `with` command.

with(plots);

On the other hand, there are times when memory is at a premium, or when
you only need a single procedure from the package. In that case it is
probably better to load only what you need. In that case you can
call a procedure by naming the package in which it resides, followed
by the procedure name in brackets. Remember that this is just
a long way to specify a procedure: after that comes the usual argument
list.

plots[display]([plot1,plot2]);

The "final exam" for this course will take place
at 8:00 AM on Tuesday, 12 December. This will be an ordinary
50 minute test. It will be comprehensive, but weighted toward
the latter half of the semester. As always, paper notes will
be permitted, but no electronic devices will be allowed.
A sample exam is available.

A
Solution example is available
for the quiz. The solution to
Test 1 is still available too.

The ultimate assignment is posted.
