MATLAB Simulations for Radar Systems Design，此书附带源程序 (MATLAB Simulations for Radar Systems Design, the book attached to source)

说明：  一种简单的灰度图片的匹配方法，是有自己编写(A simple gray scale image matching method is to prepare its own)

matlab例程，可用的DC/DC构建方法，采用pwm进行直流端高低电压的转换(matlab routines, can be a DC/DC construction method using low voltage DC side pwm for conversion)

MIT心电数据库读取程序源码 MIT的格式不能直接在MATLAB上使使用 通过此程序源码转换成能直接应用在MATLAB上的格式 可直接使用。 (MIT ECG database reads the program source MIT' s format can not be converted to make use of this program source code can be applied directly in MATLAB format can be directly used directly in MATLAB.)

利用MATLAB进行带通数字调制与解调——M元正效幅度键控调制。(we use MATLAB for bandpass digital modulation and demodulation- M Yuan positive effect amplitude shift keying modulation to achive a good understanding.)

说明：  基于遗传算法matlab优化程序 代码基于遗传算法matlab优化程序(GA problem)

设计一个低通数字滤波器，满足如下设计指标： 通带截止频率：0.2pi，通带波动：1dB 阻带截止频率：0.3pi，阻带衰减：15dB 要求：分别采用巴特沃斯、切比雪夫Ⅰ型、切比雪夫Ⅱ型和椭圆滤波器原型进行设 计，比较各种设计的阶数、实际阻带衰减，分析实验结果 (Design a low pass digital filters that meet the following design specifications: passband cutoff frequency: 0.2pi, pass-band fluctuations: 1dB stopband cutoff frequency: 0.3pi, stop-band attenuation: 15dB requirements: respectively Butterworth, Chebyshev Ⅰ, Ⅱ and Chebyshev prototype elliptic filter design, comparing the order of the design, the actual stop-band attenuation, analysis of experimental results)

good matlab source code for the cepetrum analysis,enjoy it.(good Matlab source code for the cepetrum an alysis, enjoy it.)

根据所给定的节点值和节点上的函数值,取边界条件为 “左右两端的一阶导数值为零”, 编制构造三次样条函数的 Matlab 程序。 另附测试程序(Depending on the value of a given node and the node function value, taking the boundary conditions for the " right and left ends of the first derivative value of zero," the preparation of structural cubic spline function of Matlab procedures. Attached test program)
