Diophantine 丢番图的求解，很经典，也很简单(Diophantine)

该程序使用matlab模拟出心电图信号。(The program uses matlab simulate the ECG signal.)

用matlab实现GLG论文中的灰度图像的对比度增强算法(GLG paper to achieve the grayscale image contrast enhancement algorithm by matlab)

基于模型的反演，首先先验信息建立初始模型，然后采用模型优选迭代扰动算法，通过不断修改更新地质模型，使模型正演合成地震记录与实际地震数据最佳吻合，最后的模型数据便是反演结果(Broadband Constrained Inversion)

safari调用第三方APP demo 可以直接调试成功 供新手参考 (safari called third-party APP demo success can be directly debug reference for the novice)

进行Hilbert-Huang变换的源代码，可以对信号进行时频分析，非常好用

说明：  使用matlab有关am调制的仿真编程，基本的仿真代码(Am prepared to use the simulation on matlab programming, the basic simulation code)

In telecommunications, direct-sequence spread spectrum (DSSS) is a modulation technique. As with other spread spectrum technologies, the transmitted signal takes up more bandwidth than the information signal that modulates the carrier or broadcast frequency. The name spread spectrum comes from the fact that the carrier signals occur over the full bandwidth (spectrum) of a device s transmitting frequency.
