matlab_3D

it is for electrical engineering, expecially for power systerm. it is for NR—powerflow.

It is mainly used for fingerprint recognition in matlab

说明：  用优化算法求解运输问题。 1.不使用linprog，比较歧异解 2.用西北角法求初始基本可行解，用闭回路法确定退出基和更新运输矩阵 3.不能处理非平衡的运输问题(Optimization algorithm used to solve transport problems. 1. Do not use linprog, compare differences solution 2. With the northwest corner of France seeking an initial basic feasible solution, using closed-loop method to determine the transport out of the base and update the matrix 3. Can not handle the transport of non-equilibrium)

Adaptive Gradient-Based Methods for Adaptive Power Allocation in OFDM-Based Cognitive Radio Networks. IT IS THE RECENT PAPER IN COGNITIVE RADIO NETWORKS

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.
