信号与系统分析及MATLAB实现一书中的所有源代码，具有较高的实用价值！(Signal and System Analysis and MATLAB a book of all the source code has high practical value.)

对图片进行灰度处理，用matlab编程来实现直方图均衡化，(Gray on the picture to deal with implementation matlab programming to histogram equalization,)

Programming Exercise

此源码在matlab环境下运行。此程序功能是：输入采样频率，能够返回高斯滤波器的系数，由连续域经过采样得到离散域的高斯滤波系数。(This source in the matlab environment. This program features are: input sampling frequency, to return the coefficient of Gaussian filter, after sampling from the continuous domain to be discrete domain Gaussian filter coefficients.)

5 algorithms in direction of arrival estimation

设计一个滤波器滤除正弦信号中的噪声，还原正弦信号。正弦信号为sin100t，噪声信号是均值为0、方差为1的高斯白噪声。信号采样频率为2000 Hz。(The design of a filter to filter out the noise in the sinusoidal signal, restoring the sinusoidal signal. Sinusoidal signal sin100t, and noise signal with mean 0 and variance 1 Gaussian white noise. Signal sampling frequency of 2000 Hz.)

通过matlab彩色图像转换成灰度图像，再图像旋转，然后画布扩大，最后均值插值(Matlab color images through the gray image into another image rotation, and then expand the canvas, and finally the mean interpolation)

nearestSPD works on any matrix, and it is reasonably fast. As a test, randn generates a matrix that is not symmetric nor is it at all positive definite in general.

基于MATLAB的升降压斩波电路的仿真，可以调节负载和占空比来观察波形的变化(Based on MATLAB buck chopper circuit simulation, you can adjust the load and duty to observe the waveform changes)
