说明：  自己根据K-MEANS思想在MATLAB下实现的彩色图像分割算法程序，用最普通的语句实现，通俗易懂。可以直接用于对彩色细胞图像的分割，分割结果比较准确，(K-MEANS in accordance with their own ideas in MATLAB to achieve color image segmentation algorithm based on the procedures used to achieve the most common statement, user-friendly. Can be directly used for color cell image segmentation, more accurate segmentation results,)

GSM的物理层仿真 基于matlab 采用simulink形式 非常好(GSM physical layer simulation based on matlab simulink form of very good)

运用matlab这个软件运用递归方法运算出任意一个数的阶乘(The use of this software using a recursive method matlab computing factorial of a number of arbitrary)

希尔伯特变换hilbert得到的解析信号，并对变换结果进行傅里叶变换，观察频谱分布(Hilbert transform to obtain the analytic signal, and transform the results of Fourier transform, observe the spectrum distribution)

对于平稳序列,运用ar模型计算其参数，并进行适应性检验。(for a smooth sequence, the use ar model parameters and adaptive testing.)

说明：  跳频是按跳频序列随机改变一个信道所占有频道频率的技术。在GSM 系统中，可利用跳频技术频率分极和干扰分极的特点，改善网络质量。引入跳频技术，可保证在网络软拥塞不上升的情况下，频率复用度较小。(FH frequency hopping sequence is based on a random channel change in the country channel frequency technology. In the GSM system, can make use of frequency hopping technology sub-polar and polar characteristics of interference and improve network quality. The introduction of frequency-hopping technology to ensure that congestion in the network does not increase in the soft case, a smaller frequency reuse moment.)
