gets the value of an environment variable.

Some common algorithms

把数据从text文件中分离并生成矩阵，同时显示text中的文字(Data from text files and generates separate matrix, while the text display text)

BLIND SOURCE SEPARATION

ARMA有理谱估计的阶数估计，用于估计用ARMA过程估计功率谱时要用几阶比较合适。(ARMA spectrum order estimation. It is used to compute the order of ARMA process that suited for signal estimation. )

agglomorative clustering

使用matlab完成harris corner检测，探测出边界点(Use matlab completed harris corner detection, detection of boundary points)

This is a JPEG encoding & decoding program of still image. It does not use level shifting. Discrete Cosine transform (DCT) is performed both by classical & Chen s Flowgraph methods. Predefined JPEG quantization array & zigzag order are used here. RUN - LEVEL coding is used instead of Huffman coding. Compression ratio is compared for each DCT method. Effect of coarse and fine quantization is also examined. The execution time of 2 DCT methods is also checked. In addition, most energatic DCT coefficients are also applied to examine the effect in MatLab 7.4.0 R2007a. Input is 9 gray scale pictures & output is 9*9=81 pictures to compare. Blocking effect is obvious. (This is a JPEG encoding & decoding program of still image. It does not use level shifting.
