频率分析程序 检测信号中的多个频率分量(frequency analyse detective more than one frequency)

自适应多速率编码器标准代码，编码端。可将wav文件编码生成amr格式的文件。这种格式的文件可根据信道质量，自动调节编码速率，故称之为自适应。(adaptive multi-rate coding standards for code-coding. Wav documents can be generated amr coding format documents. This format of the document is available according to the channel quality, automatic adjustment coding rate, but it is called adaptive.)

提供一种求解最优哈密尔顿的算法---三边交换调整法，要求在运行jiaohuan3（三交换法）之前，给定邻接矩阵C和节点个数N，结果路径存放于R中。 bianquan.m文件给出了一个参数实例，可在命令窗口中输入bianquan,得到邻接矩阵C和节点个数N以及一个任意给出的路径R,，回车后再输入jiaohuan3,得到了最优解。 由于没有经过大量的实验，又是近似算法，对于网络比较复杂的情况，可以尝试多运行几次jiaohuan3,看是否能到进一步的优化结果。 (Provide an optimal algorithm Hamilton- trilateral exchange Adjustment Act, requiring running jiaohuan3 (c exchange) before a given adjacency matrix C and the node number N, the results of the path stored in the R in. bianquan.m document gives examples of a parameter can be in the command window, type bianquan, be the adjacency matrix C and the node number N and an arbitrary given path R,, carriage return after the input jiaohuan3, have been the optimal solution . After the absence of a large number of experiments, it is approximate algorithm, for more complex network situations, you can try to run several jiaohuan3, can look to further optimize the results.)

说明：  算谐振频率的一个小程序，并结果附图，很有参考价值(Operator resonant frequency of a small program, and the results of drawings, of great reference value to)

Watermarking, as opposed to steganography, has an additional requirement of robustness against possible attacks. An ideal steganographic system would embed a large amount of information perfectly securely, with no visible degradation to the cover object.
