《MATLAB神经网络30个案例分析》中的第13个例子，案例13 SVM神经网络中的参数优化---提升分类器性能。希望对大家有一定的帮助！(The MATLAB neural network analysis of 30 cases of example, 13 cases of 13 SVM parameters optimization of neural network classifier performance- ascension. Hope to have certain help to everybody! )

地震反应谱计算方法，可以对于地震进行预测监控，方便及时进行相关措施减少人员伤亡和财产损失。(The calculation method of seismic response spectrum, earthquake prediction can be convenient for monitoring, timely measures to reduce casualties and property losses.)

用于机械原理课程中对RRR结构的运动分析，可用于计算位移、速度、加速度(Courses for mechanical principle of the movement structure of the RRR analysis, can be used to calculate the displacement, velocity, acceleration)

该模型是基于实地测量的即以准平坦地形、大城市市区的中值场强或路径损耗作为参考，对其他传播环境和地形条件等因素分别以校正因子的形式进行修正，用来预测地面移动系统信号的强度。其频率适用范围是150MHz到1000MHz的UHF/VHF频带。目前使用的主要频段资源为800~900MHz。这一频段，在相对平坦区域，一般可应用Okumura-Hata传播模型。Hata提供了对这些数据的解析逼近，并捕捉到大部分的主要影响(The model is based on field measurements of the quasi-flat terrain, large cities in the urban field strength or path loss values as a reference for other dissemination of environmental and topographic conditions and other factors correction factor respectively in the form of amendments to be used to predict the ground mobile systems the signal strength. The frequency range is 150MHz to 1000MHz for the UHF/VHF band. The main bands currently used resources for the 800 ~ 900MHz. The band, in the relatively flat areas, generally can be applied to Okumura-Hata propagation model. Hata provides these data analytic approaches, and to capture most of the major impact)

这个是关于OFDM系统的信道估计的算法的两种方法，分别是OFDM的最小二乘和最小均方误差估计的仿真程序代码(the OFDM system is on the channel estimation algorithm of the two methods OFDM are the least squares and minimum mean square error estimate of simulation code)

1、读取显示所给PET图像（SE2IM210）。 2、学习imhist函数，画出所给PET图像的直方图。 3、根据直方图为该PET图像选择合适的显示窗（imshow参数），使胸 部轮廓等解剖结构可见。 4、根据直方图选择合适阈值，分割肿瘤区域与正常区域，计算肿瘤区 域内图像灰度均值、方差、最大值及最小值。(1 give PET images displayed, read (SE2 IM210). 2, learning, imhist function, draw the give PET image histogram. 3, according to the histogram for the PET image to choose the appropriate display window (imshow parameters), make bosom Outline of anatomical structures such as visible. 4, according to the histogram, choose appropriate threshold segmentation tumor area and normal area, calculating the tumor area In the domain of image grayscale average and variance, the maximum and minimum values.)

以matlab撰写的ACO算法，很适合用于研究Ant colony algorithms。(Write a MATLAB program to solve the following given city Euclidean traveling salesman problem (given lattice points) by using ant-cycle algorithm.)

这个与相应的教材相对应的matlab代码，如果有需要的可以下载，免去手动输入的麻烦(This matlab code corresponding with the corresponding textbook, if need can be downloaded, eliminating the need to manually enter the trouble)
