用matlab实现了一个通用的数学模型，人口增长模型(Using matlab to achieve a common mathematical model, population growth model)

matlab用户图形界面用法的一个小例子。用到了文本框、滚动条等控件，对刚开始学习matlab有一定的帮助。(matlab graphical user interface uses a small example. Used in the text boxes, scroll bars, and other controls, just started learning matlab have some help.)

matlab的基础教学。对初学者有帮助。(matlab basis of teaching. For beginners)

通过时频转换法来，来画BPSK巴克码的模糊函数，tao（时延）切面，fd（多普勒频移）切面。以及其模糊度图的画法(Through the time-frequency conversion method to draw Barker code BPSK ambiguity function, tao (delay) section, fd (Doppler shift) section. And its ambiguity diagram drawing)

PERT Schedule Calculation Method MATLAB CODE

对样本进行主成分分析： 把原来多个变量划为少数几个综合指标的一种统计分析方法，是一种降维处理技术(Principal component analysis on the samples: the original more than one variable is designated as a few indicators of a statistical analysis method, a dimensionality reduction processing technology )

这个程序主要针对信号的调制与解调进行的编程，感觉很实用。(This program targeted signal modulation and demodulation for the program, feeling very practical.)

PROGRAM IS USED FOR Interface matrix keyboard with 8051.

Neural network Perceptron For Xor classification

说明：  实现利用高斯分布聚类，即完成em算法，直接在matlab上运行，可以作图直观显示（二维数据）(Achieve Gaussian distribution clustering, complete em algorithm, running directly on matlab, you can visualize mapping (two-dimensional data))
