This is a collection of m-files I created to complete a research project into the DC components of various encoding techniques. Eight of the files create random bit sequences that conform to their coding requirements. The others were files I found useful in the scope of the project and supplement the generating m-files.

This some optimization to use MATLAB matrix notation. others may find a way to further optimize the nested loops.
Anyone who interacts with today s modern databases needs to know SQL (Structured Query Language), the standard language for generating, manipulating, and retrieving database information. In recent years, the dramatic rise in the popularity of relational databases and multi-user databases has fueled a healthy demand for application developers and others who can write SQL code efficiently and correctly.
Hidden_Markov_model_for_automatic_speech_recognition
This code implements in C++ a basic left-right hidden Markov model
and corresponding Baum-Welch (ML) training algorithm. It is meant as
an example of the HMM algorithms described by L.Rabiner (1) and
others. Serious students are directed to the sources listed below for
a theoretical description of the algorithm. KF Lee (2) offers an
especially good tutorial of how to build a speech recognition system
using hidden Markov models.
Returns weighted percentiles of a sample given the weight vector w
％ The idea is to give more emphasis in some examples of data as compared to
％ others by giving more weight. For example, we could give lower weights to
％ the outliers.
％ The motivation to write this function is to compute percentiles for Monte
％ Carlos simulations where some simulations are very bad (in terms of goodness
％ of fit between simulated and actual value) than the others and to give
％ the lower weights based on some goodness of fit criteria.

J2K-Codec ver 1.9
=== === === === === === === === =====
Make your graphics look better with an easy-to-use
JPEG 2000 decoding component. J2K-Codec can help
game developers, screensaver creators and many
others to improve their products--to achieve better
image quality and reduce installation package size.
The new image compression standard based on wavelet
technology has many interesting features not
available in the old JPEG, such as alpha-channel
and varied resolution levels.
The first edition of this book ranks among the small (very small) number of books that I credit with significantly elevating my skills as a professional software devel-oper. Like the others, it was practical and easy to read, but loaded with important advice. Effective C++, Third Edition, continues that tradition. C++ is a very powerful programming language. If C gives you enough rope to hang yourself, C++ is a hard-ware store with lots of helpful people ready to tie knots for you. Mastering the points discussed in this book will definitely increase your ability to effectively use C++ and reduce your stress level.

linux下用C語言寫的聊天程序！/*BUG and NOTE:
Not join protect to Shared Memory Segments,example Semaphore Arrays.
Not check the parameters validity.
When transmit may be error.
If the client program no right exit,others cannot know,the service program shouldbe check the client program whether exist timing.
The program when exit(), it do not delete the Shared Memory Segments,you maybe use atexit() but the program have some processes.
When one process is exit(),others is continue.
The service program s action is few.
And so on. */
