这是一本关于matlab程序设计与应用的书的源代码，里面有很多类型的程序，大家可以学习下，很多程序都非常好用(This is a matlab program design and application of the book' s source code, there are many types of programs, we can learn, many programs are very easy to use)

Hello friend how are you. Its a Xamrine Sample Clock Example. Its a Analog clock

QPSK_Gardner位定时同步算法的简单仿真，其中的环路滤波器部分参数设计不太合理，但是基本能实现效果。(Simple emulation QPSK_Gardner bit timing synchronization algorithm, which some parameters of the loop filter design is not reasonable, but the basic effect can be achieved.)

模式识别中K均值聚类分析算法的matlab实现及注释，其中采用了误差平方和判断。(K-means clustering analysis algorithm in pattern recognition of matlab and annotation, which adopts the error sum of squares of judgment)

用于空间数据分析中的Kf计算，并坐车相应的图形(Spatial data analysis for the calculation of Kf, and the corresponding graphic car)

捷联惯导系统的matlab程序源代码，包含输出代码，非常好用(The SINS matlab program source code, including the output code, it is very easy to use)

i am in need 4g related matlab code.i learning in area of lte-advanced downlink for writing the matlab code

研究了基于信号强度模型的室内定位技术. 通过运用线性回归、补偿式线性回归和多元回归方法，利用 仿真数据建立了信号强度模型.(Indoor positioning technology based on signal strength model by using linear regression, the compensated linear regression and multiple regression method using simulation data signal strength model.)

This code is an implementation of SURF (Speeded Up Robust Features). SURF will detect landmark points in an image, and describe the points by a vector which is robust against (a little bit) rotation,scaling and noise. It can be used in the same way as SIFT (Scale-invariant feature transform) which is patented. Thus to align (register) two or more images based on corresponding points.

说明：  非正弦信号的波束形成程序，和利用相位的常规波束形成不同，非正弦信号的波束形成首先匹配滤波，提取包络，然后延时相加，(Non-sinusoidal signal beamforming process, and the use of conventional beam-forming phase is different from non-sinusoidal signals in the first match beamforming filtering, envelope extraction, and then add delay,)
