Huffman codes In telecommunication, how do we represent a set of messages, each with an access frequency, by a sequence of 0’s and 1’s? To minimize the transmission and decoding costs, we may use short strings to represent more frequently used messages. This problem can by solved by using an extended binary tree which is used in the 2- way merging problem.

SuperLU is a general purpose library for the direct solution of large, sparse, nonsymmetric systems of linear equations on high performance machines. The library is written in C and is callable from either C or Fortran. The library routines will perform an LU decomposition with partial pivoting and triangular system solves through forward and back substitution. The LU factorization routines can handle non-square matrices but the triangular solves are performed only for square matrices. The matrix columns may be preordered (before factorization) either through library or user supplied routines. This preordering for sparsity is completely separate from the factorization. Working precision iterative refinement subroutines are provided for improved backward stability. Routines are also provided to equilibrate the system, estimate the condition number, calculate the relative backward error, and estimate error bounds for the refined solutions.

Reads/writes text as a character stream, buffering characters so as to provide for the efficient reading/writing of characters, arrays, and lines. The buffer size may be specified, or the default size may be used. The default is large enough for most purposes. In general, each read request made of a Reader causes a corresponding read request to be made of the underlying character or byte stream. It is therefore advisable to wrap a BufferedReader around any Reader whose read() operations may be costly, such as FileReaders and InputStreamReaders.

This GUI is an updated and enhanced version of the “StructBrowser” utility submitted to MatLab Central in may 2003. It comes with new interface and an enhanced display. It uses Microsoft TreeView control to display and explore any kind of MatLab structures. The CRC ExploreStruct was designed to expose the contents of the array struct to any depth and plot any of the components. This tool is very useful for programmers using structures in their code

The major functionality added in this release includes: - Rootless mode in X11 - Widget Templtes [both compiled and XML] As always, this isn t meant to be a stable release, it is only provided so people can more easily experiment with PicoGUI and possibly help in its development. Some of the more significant known bugs: - The PicoGUI laucher may not work right now, it s undergoing some change. - Several of the apps included here are not finished, not started, or otherwise broken. - There is a redrawing bug that may cause flickering on some platforms

Modern C++ Design is an important book. Fundamentally, it demonstrates generic patterns or pattern templates as a powerful new way of creating extensible designs in C++--a new way to combine templates and patterns that you may never have dreamt was possible, but is. If your work involves C++ design and coding, you should read this book.
