naville法，雅各比法，牛顿法，CG法等等数值分析课程中使用的Matlab程序。(naville method, Jacobi method, Newton method, CG method, etc. used in numerical analysis courses Matlab program.)

Compute log(sum(exp(x),dim)) while avoiding numerical underflow. By default dim = 1 (columns).

说明：  最优化算法中得拟牛顿法和共轭梯度法,以及Armijo型搜索和最优步长搜索。(Congradient and NiNewton algorithms in optimazation based on MATLAB)

针对当前存在的大量数值型数据，将连续型数据离散化，有利于计算机直接处理变量。(In view of the existence of a large number of numerical data, the discretization of continuous data is conducive to deal directly with the variable computer.)

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.
