These are orthogonal complimentary code version of walsh codes which are or to be used in cdma systems.

一个100*100的正方形，用半径为10的圆覆盖，随机在100*100的平面内放置圆心，问至少需要多少个圆，才能使得成功覆盖整个区域的概率在95 以上？并给出一个均匀随机放置装置的分布图。(A 100* 100 square, a circle with a radius of 10 covers, 100* 100 randomly placed on the center plane, and asked how many circles at least, to cover the entire area so the probability of success of 95 or more? And gives a uniform distribution of randomly placed devices.)

用matlab编写波前编码系统光学传递函数mtf在不同离焦下随相位板参数的变化曲线(the curve of mtf along with the change of phase plate parameters under different focal )

用于模拟光纤光栅(FBG)的反射特性和时延特性,特别是用于模拟各种切趾包络下光纤光栅的反射和时延特性。(Used to simulate the fiber Bragg grating (FBG) of the reflective properties and delay properties, especially for simulation of various apodization envelope under the fiber grating reflection and delay characteristics.)

MST问题求解程序, 采用Matlab实现, 源程序.(MST problem source code , MST problem free code)

附件1是关于FFT算法的详细编程，及详细原理讲解，个人认为，这篇论文对从事信号处理，频谱分析很有帮助，特使是进一步理解FFT算法，很有必要阅读。 程序+原理+运行！ 附件2是关于直接运行FFT工具箱进行频谱分析，请大家可以参考对照，对理解FFT算法肯定有帮助！ (matalb fft 频谱分析)

灰色模型的背景值和求导过程的联合优化，效果非常不错(Joint optimization model and gray background value derivation process, the effect is very good)
