GPS捕获过程中的相干积累算法的matlab实现(GPS MATLAB)

本文主要讨论了各种提高matlab程序运行速度的方法与技巧。(This paper discusses the methods and techniques of the ways of increasing the the matlab program running speed.)

MATLAB中典型的霍夫变换检测圆，非常的经典的案例(MATLAB typical Hough transform circle detection, very classic case)

利用MATLAB实现分水岭算法得到图像分割(Watershed algorithm)

阶比分析文件。特别适合对数据进行处理，特别别是信号处理。(Order analysis files. Particularly suitable for data processing, signal processing is not particularly.)

比较DFT,小波分析，hht算法分析调频信号的异同(Comparison of DFT, wavelet analysis, hht similarities and differences between the FM Signal Algorithm Analysis)

利用差分方法求解带状线的特性阻抗等信息，适合初学者(The use of finite difference method for solving the characteristic impedance stripline information, suitable for beginners)

simulink做的BPSK的调制与解调，信号源是随机信号与PN码扩频调制，最后结果与随机信号比较一致(simulink do BPSK modulation and demodulation, the signal source is a random signal with the PN code spread-spectrum modulation, the final result more consistent with the random signal)

Comparison of two survival curves can be done using a statistical hypothesis test called the log rank test. It is used to test the null hypothesis that there is no difference between the population survival curves (i.e. the probability of an event occurring at any time point is the same for each population).

说明：  这是MPM算法，用MATLAB实现的，需要简单修改一下。这个对于mkv算法的实现是很重要的。(This is the MPM algorithm, using MATLAB to achieve, requires simple corrections. Mkv algorithm for the realization of this is very important.)
