make universal codebook for contourlet

根据已给ecg数据文件，画出心电图波形，并自动标记出特征点位置，并计算P-R时间间隔 等参数。 附件是.dat为数据文件，为二进制文件，每2个字节代表一个采样点，采样频率1000hz。依 次为1-12导联的第一个采样点，其次是1-12导联第二个采样点，.... .hea头文件是文本格式说明文件，可以看到十二导联存放的先后顺序。 (According to the data file has to ecg, draw the ECG waveform, and automatically mark the feature points, and calculate parameters such as PR interval. The attachment is. Dat for data files, binary files, each 2 bytes represent a sampling point, the sampling frequency 1000hz. Followed by a 1-12 lead in the first sampling point, followed by 1-12 second sampling point lead ,..... Hea header file is a text file format that you can see the sequence)

LFM信号的匹配滤波器,用于信号距离探测(LFM the matched filter for signal detection distance)

matlab上机实验：时域采样与频域采样(Time domain sampling and frequency domain sampling )

这个函数求热传导方程初值问题的解，以输入图像为初始值，输出图像为t时刻的解，输出图像被用来作为去噪的结果(This function for heat conduction equations of the solution of the initial boundary value problems, with input image for the initial value, output image of the solution of the moment for t, output image to be used as a result of the noise )

说明：  功率谱估计随机数字信号处理中的另一个实验，以太阳黑子估计太阳活动的周期(Power spectrum estimation random digital signal processing in another experiment, in order to estimate the solar sunspot activity cycle)

说明：  基带传输常用码的编码解码MATLAB方法 (baseband transmission )

这是一本研究目标定位跟踪的学习手册（在雷达，声纳，无线传感器网络领域等），采用的方法有最小二乘/极大似然，卡尔曼滤波，蒙特卡洛，粒子滤波等方法，更是很多读者需要的是里面有大量的仿真实例和程序代码，并配以中文注释，读者可以结合书中的原理和公式，对程序有进一步的理解。也适合很多读者在已有的代码的基础上对算法进行改进。(This is a study targeting the learning manual tracking (radar, sonar, wireless sensor networks, etc.), using the least squares method/maximum likelihood, Kalman filtering, Monte Carlo, particle filtering methods , but many readers need is there are a large number of simulation examples and program code, and with Chinese notes, the book the reader can combine the principles and formulas, a better understanding of the program. Also suitable for many readers on the basis of the existing code to improve the algorithm.)

Perceptron implementation, with basics characteristics and comented in portuguese, every detail.

说明：  Experimental and Modeling Studies of a Brillouin Amplifier文献中的数值模拟部分的matlab代码实现(Matlab code implementation of numerical simulation in literature of Experimental and Modeling Studies of a Brillouin Amplifie)
