CHAPTER5

matlab basic book ,介绍一些关于matlab 的知识以及其用法，对于初学者强烈推荐，可作为入门教程，有比较多的例子(matlab basic book, some knowledge on matlab and its usage, strongly recommended for beginners and can be used as entry-course, there are more examples of)

对图片中的各种几何图形进行识别，包括圆形，正方形，矩形，六边形，菱形等(On the picture to identify the various geometric shapes, including round, square, rectangular, hexagonal, diamond, etc.)

用于去除背景，得到原图与背景相减的图像并二值化(To remove the background, the subtraction image and background image and binarization)

matlab信号处理，源代码和详细注释吗，信号处理入门必备知识(matlab signal processing, source code and detailed notes this Introduction to signal processing necessary knowledge)

2D Fourier变换在光衍射方面的应用一例,对孔函数直接应用FFT2,得到衍射结果；以及FDTD方面的两个不成熟的程序(2D Fourier Transform-ray diffraction case of the application of direct application Kong FFT2 function, be diffraction; FDTD and the two immature procedures)

offset quadrature amplitude modulation

Wireless Sensor Networks have been proposed for a multitude of location-dependent applications. For such systems, the cost and limitations of the hardware on sensing nodes prevent the use of range-based localization schemes that depend on absolute pointto- point distance estimates. Because coarse accuracy is sufficient for most sensor network applications, solutions in range-free localization are being pursued as a cost-effective alternative to more expensive range-based approaches.

half band filter code

这个是silabs的芯片si1010的发射单音信号的实例，因为涉及保密，所以修改了一部分，测试可用(This is an example of the tone signal transmitter chip si1010 silabs, and because it involves confidential, so modify the part of the test can be used)

求解矩阵的LU分解和逆，两种一般方法求解线性方程组的解。(LU matrix factorization and solving the inverse, two general methods for solving linear equations.)
